| Question | Answer |
|---|---|
| Alkali Metals | the elements in Group 1 of the periodic table; most radioactive metals; their atoms have 1 electron in their outer level |
| Alkaline-earth metals | the elements in Group 2 of the periodic table; are radioactive but not as much a alkali; atoms have 2 electrons in their outer level |
| Transition Metals | atoms in this group give away electrons easily, and they do not have individual names |
| Boron Group | includes the most abundant metal in Earths’ crust |
| Carbon Group | used in making computer chips, also not very reactive |
| Nitrogen Group | 5 electrons on the outer layer, and reactivity varies among them all |
| Oxygen Group | reactive, all except for oxygen are solid at room temperature |
| Halogens | the elements in Group 17 of the periodic table; they are very reactive nonmetals, and their atoms have seven electrons in outer level |
| Noble Gases | the unreactive elements in Group18 of the periodic table; atoms have 8 electrons in outer level except helium with 2 |
| Hydrogen | reactive element with only one electron that is a gas at room temperature |
