| Question | Answer |
|---|---|
| Alkali metals | soft, slivery colored, very reactive, one valence electron. |
| Alkali earth metals | fairly reactive, make earth's crust, 2 valence electrons |
| transition metals | good conductors, maletable |
| metaliods | share many metal and non-metal qualities, semi-conductors |
| non-metals | brittle, do not conduct electricity |
| halogens | posionous, fairly reactive, missing one valence electron |
| noble gases | unreactive, glow in electricity, full outer shell. |
| group | same number of valence electrons |
| period | same amount of electron shells. |
