| Term | Definition |
|---|---|
| Atomic radius | Atomic size decreases from L to R across a period. Due to the increase in z_eff. Which pulls the e- closer to the nucleus atomic size. Increases as you move down a group. Additional shells are added, increasing the distance between e- and nucleus |
| Z_eff | net pos. charge felt by electron) |
| Ionization Energy | Increases from L to R, as the atomic size decreases and Z_eff increases harder to remover e-. Decreases down a group. |
| Electron Affinity | Becomes more neg. (more energy is released) as you move L to R. Becomes les neg. (less energy is released) as you move down a group |
| Electronegativity | Increases from L to R. Decreases as you move down a group |
