10. What is a pure substance? Is a substance in which there is a uniform composition of “particles”. The particles we are talking about are atoms.

13. What is an element? meet the elements song A substance that Contains only one type of atom. All known elements are organized on the periodic table of elements. atoms and elements

14. What is a compound? Is a combination of elements that come together through a chemical reaction and becomes something called a molecule.  A molecule is two or more different elements combined in a specific ratio.
