| Question | Answer |
|---|---|
| Atomic Radius | The distance from the center of the nucleus to the outer most electron. |
| Atomic radius increases down a group because | There is more energy levels. |
| Atomic radius decreases across a period because | There are more protons pulling on the electrons. |
| Ionization energy | The energy needed to remove electron. |
| Ionization energy decreases down a group because | The atom is bigger so the electron is easier to remove. |
| Ionization energy increases across a period because | The atom is smaller so the electron is harder to remove. |
| Electronegativity | The ability to attract more electrons. |
| Electronegativity decreases down a group because | its harder to attract when its bigger. |
| Electronegativity increases across a period because | Its easier to attract when its smaller. |
| Metal reactivity increases down a group and decreases across a period because | Its easier to lose electrons if its bigger/ if the atomic radius is bigger |
| Nonmetal reactivity decreases down a group and increases across a period because | Its easier to gain electrons if its small/ if the atomic radius is smaller |
