For this question you have to know how to identify the element and you have to understand how reactivity works.

# data[].attributes.body
The question asks for neutrons but they don't give you neutrons. You have to know how to calculate to find the answer.

# data[].attributes.body
because you had to know where your reactive element is at and have to know how to indentify the element.

# data[].attributes.body
I think that question 1 was harder because I didnt know what Na was

# data[].attributes.body
It was hard because you needed to caculate the numbers.

# data[].attributes.body
I believe that question 2 was harder because you have to find the mass and subtract the number of protons to the mass number

# data[].attributes.body
The second one because i didnt get it

# data[].attributes.body
you have to know how to identify a element and how reactive it is.

# data[].attributes.body
I think this because you had to find the neutrons and to do that you had to have the protons subtracted from the mass. The first is just which one is the right element and reactivity of it

# data[].attributes.body
Between these two questions I say question 2 is harder because you would need to know what to subtract. As in what numbers to use. I understand because i know to subtract the mass number and protons

# data[].attributes.body
you have to do more work because you have to subtract

# data[].attributes.body
I think question 1 was harder because he might not have known what element Na was

# data[].attributes.body
It was more difficult because there was subtraction involved

# data[].attributes.body
i would say this one because you need to know what method to use and you cant find this on the reference sheet you have to memorize it

# data[].attributes.headline
This may be hard because it is easy to mix up elements on the periodic table. To solve this you will find the atomic number that you are looking for on the table, then evaluate the group number to see if it is highly reactive (1 and 17). Also you are able to find elements that are similar in reactivity and property because they are in the same group.

Question #2 was probably more complex because you have to know how to find the amount of neutrons with your given values and you could always make one small mistake, altering your answer.

# data[].attributes.body
It was more complex because it had more steps and it recuired a periodic table, but I understood it because I followed the directions to identify the element and it's reactivity

# data[].attributes.body
Question 2 was more complex because you had to subtract and that can esaly messed uo

# data[].attributes.body
You have to do math.You have to subtract the nuber of protons for the atomic number which will give you the number of nuetrons.

# data[].attributes.body
I think question 2 was more complex because you could mess up on calculating the amount of neutrons.

# data[].attributes.body
It was open answer, and it is hard to know how to get the number of protons

# data[].attributes.body
Question 1 was harder because even if you got the proper element you could have gotten it wrong if you didn't know how reactive the element was. I understood it because I realized there were two ones with the same one so I knew the reactivity of the element.

# data[].attributes.body
I think this is more complex because reactivity can be a tricky thing to understand, and in order to get it right, you have to understand it. Even though it is kind of easy to understand.

# data[].attributes.body
Because you need to find the  mass and then subtract that with the Atomic # to get the # of neutrons

# data[].attributes.body
I think this one is more complex because you have to calculate stuff instead of just knowing the periodic table.

# data[].attributes.body
i thought that this one was harder because technically there could be more than one answer

# data[].attributes.body
While I believe this question is more straightforward, I also think it will take many more steps which makes it easier to mess up.

# data[].attributes.body
I think question one was more complex because it was 2 possible answers

# data[].attributes.body
I think number one was a harder becuase it there were two answers

# data[].attributes.body
You have to find the amount of protons or electrons to find the element, and then decide what group it is in and how reactive it is. Reactive is 1 and 17, not reactive is 18

# data[].attributes.body
Because you have to do multiple things in order to find out which can be complicated.

# data[].attributes.body
because you need to find the name of the element

# data[].attributes.body
question 2 is harder because you need to know the formula and also you need to calculate the numbers

# data[].attributes.body
You have to know the formula to find neutron ( mass - proton ) .

# data[].attributes.body
I thought question two was harder because it easy to get mixed up or misguided if you dont read it right

# data[].attributes.body
Even though they were both not hard, I felt that this one is the hardest because it gives you multiple sources to work from.

# data[].attributes.body
It was question one b/c it was hard to know how reactive it was.

# data[].attributes.body
for this questions youy have to know how to do math

# data[].attributes.body
math you had to do math,

# data[].attributes.body
Question 2 was little complex because I had to do multi step to solve problem. I Subtract to solve

# data[].attributes.body
question 1 is harder because not always the protons tell you

# data[].attributes.headline
Question 1  is harder because you have to know the reactivity works and the element.

# data[].attributes.subject
Question 1  is harder because you have to know the reactivity works and the element.

# data[].attributes.body
i think it was hard because boby had to guess on the question so that confers that more people can guess

# data[].attributes.body
since you had to find the element and the valence electron

# data[].attributes.body
cause i can see how he could of got it wrong cause he thought all the numbers was the same

# data[].attributes.body
i think question 2 was hard because there was 3 numbers

# data[].attributes.body
i think this was the hardest bc people dont know what to do w the numbers

# data[].attributes.body
It was hard for him because he guest

# data[].attributes.body
Number one is harder because you have to name how reactive it is.

# data[].attributes.body
Number one was hard because we need to know if its reactive or not.

# data[].attributes.body
I feel like number one is harder for Bob because he had to identify the element and remember which groups are the most reactive.

# data[].attributes.body
I think that question 1 is more complex because there is more to do. like looking at the periodic table and knowing that groups 1 and 17 is highly reactive.

# data[].attributes.body
most complex for bob

# data[].attributes.body
this was more complex because it involved math for bob.

# data[].attributes.body
most complex for bob

# data[].attributes.body
I think question 2 is more complex for Bob since finding the neutron is harder since it's not on the periodic table.

# data[].attributes.body
The most complicated problem for bob I think is the first question, since you have to identify the element and the reactivity of the group.

# data[].attributes.body
Number 2 was easy because all you had to do was subtract 36 from 84. ;-;-; easy peasy

# data[].attributes.body
This one is harder because  there are multiple things you need to look out for to find the answer
-leslie cady

# data[].attributes.body
It was more comlpex for Bob.

# data[].attributes.body
I think Question 1 was harder than Number 2 since you have to explain more & more to do

# data[].attributes.body
I can infer that the 2nd question was the most complex seeing that you have to know how the equations work with the given information

# data[].attributes.body
f0r b0B;-;

# data[].attributes.body
it is complex cause you have to do math

# data[].attributes.body
Had to do more steps for number 2 than number 1.

# data[].attributes.body
You have to subtract and that takes to much word

# data[].attributes.body
Pretty hard for bob

# data[].attributes.body
I think this one would be harder for people because people would get more mixed up with the protons and neutrons.

# data[].attributes.body
question 1 was the most complex bc you had to get the periodic table and search for it .

# data[].attributes.body
I think question 2 is more complex because with question 1 you just have to look at the periodic table, but for question 2 you have to calculate.

# data[].attributes.body
i think #2 is harder because what if bob doesn't know how to add and if he doesn't remember A.P.E. M.A.N you need to calculate

# data[].attributes.body
I think question one is more complex since learning the periodic table is easier said than done

# data[].attributes.body
because you had to know where your reactive element is at and have to know how to identify the element.

# data[].attributes.body
I think it is one because you had more steps to determine the answer compared to #2

# data[].attributes.body
Question 2 is more complex because you need to know the formula in order to find out the number of neutrons. He needs to know A.P. E. M. A. N. or else he can't calculate depending on the question.

# data[].attributes.body
it asks you for the neutrons but they don't give it to you. you have to find it using protons or electrons

# data[].attributes.body
I think #2 is harder because you need to use math and if you subtract or add wrong you will get the wrong answer

# data[].attributes.body
Question 2 was harder because you actually had to think through what formula you need to use. Also you actually have to do math

# data[].attributes.body
I think #2 was more complex because in this question you had to be able to identify and know what the subatomic particles are, and after that you had to do math. IN question #1 all you had to do was look for the element with the atomic # of 11.

# data[].attributes.body
you need to know the equation of atomic number minus protons for neutrons

# data[].attributes.body
#2 was harder because what if we dont remember ape man

# data[].attributes.body
You have to calculate and do more work

# data[].attributes.body
I think this question is a little bit more complex because you have to know what the mass is, how many protons there are, you have to know what to add or subtract and it includes math.

# data[].attributes.body
harder because you need to know more things

# data[].attributes.body
This question was more complicated because it not only requires knowledge and understanding about reactivty but also more steps to complete it correctly.

# data[].attributes.body
Adding and subtracting is too much work to find neutrons ;-;

# data[].attributes.body
this one i think that is much harder because you need to know the right calculations to solve to get your answer and its easy to make a mistake on this.
