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 |
