| Metals | On left side of table. Generally solids conduct heat & electricity. Like to donate electrons & makes it more positive |
| Non-metals | On right side of table. Some are solids, gases, & 1 liquid |
| Non-metals 1 | Poor electrical and heat conductors. Like to gain electrons making it negative charge |
| Metalloids | Dividing line between metals & non metals. They have properties of both metal & nonmetals |
| Column 1-Alkalai Metals | Highly reactive. +1 charge |
| Column 2-Alkaline Earth Metals | Highly reactive. +2 charge |
| Column 3-12 Transition Metals | More complex group. React with lose electrons |
| Column 17-Halogens | Highly reactive -1 charge |
| Column 18-Noble Gases | Non-reactive |
| Column 13 | +3 Charge |
| Column 14 | +4 or -4 Charge |
| Column 15 | -3 Charge |
| Column 16 | -2 Charge |
| Atomic Number | Unique for each element. Gives # of protons & # of electrons. Ex. Chlorine is 17 |
