| Atom | building block of matter made of protons, neutrons, and electrons |
| compound | two or more different kinds of atoms bound together to make new stuff |
| proton | found in nucleus, positive charge |
| electron | found orbiting nucleus, negative charge |
| neutron | found in nucleus, no charge |
| ________ : same kind of atom, different number of neutrons | isotopes: same kind of atom, different number of ____ |
| ion | atom that his gained or lost electrons, has a charge |
| cation | atom that has lost electron(s) positive charge |
| anion | atom that has gained electrons, negative charge |
| covalent bonds | atoms share pairs of electron |
| ionic bounds | cation and anion are attracted to each other |
| molecule | atoms joined together in covalent bond |
| speed with a directional designation | velocity |
