2 What do we call the smallest unit of an element that has the properties of that element?

3 Atom

4 What do we call the central part of an atom, made up of neutrons & protons?

5 Nucleus

6 What do we call one of the very small parts in the nucleus of an atom that carries a positive electrical charge?

7 Proton

8 What do we call one of the extremely small parts in the nucleus of an atom that has no electrical charge?

9 Neutron

10 What do we call a tiny particle that moves around the nucleus of an atom? (It carries a negative electrical charge.)

11 Electrons

12 In chemistry, what do we call a substance that is made of only one kind of atom and cannot be split into a simpler substance?

13 Element
