1. Explain why the particle model of matter is important
2. What is an element
3. How many classifications can elements be classified and what are they
4. Where are the metals on the periodic table
5. What properties do most metals have
6. What is independent variable
7. which variable does not change during the experiment
8. what is physical change
9. what is chemical change

-----------------------------------------------------------------
Answers
1. because the particle model of matter can explain the properties of different states of matter, the relationship between energy and states of matter, how the change of energy affects matter and particles in the model can be elements or compounds or mixtures.
2. An element is a pure substance which is made of only ONE type of atom
3. three elements - metals, non-metals and metalloids
4. the different types of metals are on the left and middle of the periodic table
5. metals are malleable, ductile and conducts electricity
6. the independent variable is the variable that changes during the experiment
7. the controlled variable does not change]]> 2019-05-03 02:48:27 UTC https://padlet.com/nina_simmons1/zpxkmsjgoguf/wish/356465492 tanisha, carelle https://padlet.com/nina_simmons1/zpxkmsjgoguf/wish/356465698 1) What are the first three elements?
