What kind of atoms
| Term | Definition |
|---|---|
| Valence Electrons | The electrons farthest from the nucleus: they are responsible for atoms forming compounds |
| Molecule | 2 or more atoms chemically combined |
| Compound | 2 different atoms chemically combined |
| Mixture | A combination of 2 or more different atoms or molecules that are not chemically combined |
| Covalent Bond | Chemical bond between 2 nonmetals |
| Ionic Bond | Chemical bond between a metal and nonmetal |
| Oclet Rule | Elements are stable when their valence shell is full. This can be done with 8 or in some cases 2. |
| Alkali Metals | Reactive/ Have 1 Valence Electron |
| Alkali Earth Metals | React With Water/ Have 2 valence Electrons |
| Transition | Bend Into Different Shapes/ Have 2 Valence Electrons |
| Halogens | Toxic/ Have 7 Valence Electrons |
| Noble Gases | They Don't Form Compounds/ One has 2 Valence Electrons While The Others Have 8 Electrons |
