2. All matter is made of these (what are found on the periodic table?)

3. The place where protons and neutrons of an atom are located (but not electrons)

4. This Greek came up with idea that all matter can be broken down into “Atomos”

5. This is the only element on the periodic table that has no neutrons!

6. The charge of an atom which has the same number of protons as electrons

7.  Formed the atomic theory model of the atom, thought atoms were solid round balls

9. These subatomic particles have no charge, and are located in the nucleus

10. The number which represents how many protons and neutrons there are in the nucleus of an atom of some element.

11. How many protons are in an element is known by this number, and is unique to each element.

12. The positively charged subatomic particle

13. What we call something that is 2 or more elements combined.

14. The name of area where electrons are located

15. Developed the model of the atom in which electrons orbit the nucleus in energy levels

16. The negative particle that circles the nucleus

17. The charge of something that has more electrons than protons
