It decreases from left to right and increases as you go down.

It decreases across a period and increases down a group. This is exists because it is used to find the final product.

The ionization between the nucleus which then created the electrons to become weaker which is meaning an electron is less likely to be gained. When you measure the pH levels, it shows the evidence for the trend because we used both Mg

Metals decrease down a group . Metals have low ionization rates and  evidence we have is the lab when we put in the phenolphtaliein

The Reactivity of elements decreases as you go down a group. The atom gets larger (atomic radius) going down a group and the outer shell  expands further from the nucleus. The attraction (electronegativity) between the nucleus and the electrons become weaker, so an electron is less likely to be gained. As the electronegativity decreases, so does the ionization energy using less energy making it easier to lose an electron

Increases from left to right and decreases down a group.
It exists because it makes it easy for them to lose electrons.

# data[].attributes.body
The reactivity of metals decrease from left to right ( increases down and group and decreases across a period ) and increase from top to bottom.
As the atom gets larger the electrons are pushed further out and the attraction between the nucleus and electrons grow weaker making it easier to lose an electron

Decreases across a period because they expend more energy getting rid of electrons. Increases down a group because the metals have more electrons taken away. Evidence for this trend is when you measure pH levels.

The Reactivity of metals decreases as you go left to right. The reactivity of metals increases as you go down. This is true because metals have low ionization energy. This means its easier to lose electrons.

This was seen in the demo when there was a bigger reaction each time because we kept going down the group.

Decrease from left to right across the periodic table and increases as you go down a group because  once we put the drop of phenolphthalein the calcium pH was much more higher than the magnesium. This is because of the ionization energy that the metals have.

-This helps it lose electrons
-In the lab we could see that the Mg was losing electrons

It decreases from left to right and increases as you do down  because they have lower ionization energies, therefore it's easier for them to lose electrons. This was shown in the lab when the acidity increased down the periodic table.

Reactivity increases down a group and decreases across a period. Calcium is more reactive than Magnesium (both in Group 2). Potassium is much more reactive than metals such as Copper and Nickel (in Period 4)

it decreases going left to right across a period, and increases as you go down a group. this is because they have lower ionization energies, so it's easier for them to lose electrons.  we have evidence of this from our lab yesterday when the acidity increased going down the periodic table

decreases left to right and increases as you go down a group, and this is because of the extra valance electrons placed on their outer shell that must being remove.

decreases left to right as you do down it increases  the reason why is because lower ionzation energy makes it easier to loose electron. A ex. is in our lab from yesterday when elements incrases acidty going down
