| Question | Answer |
| Rows are also called... | Periods |
| How many rows are on the Periodic Table? | Seven |
| Columns on the Periodic Table are called... | Groups |
| Group IA | Alkali Metals |
| Group IIA | Alkaline Earth Metals |
| Group VIIA | Halogens |
| Group VIIIA | Noble Gases |
| Characteristics of Alkali Metals | highly reactive (s1) |
| Characteristics of Alkaline Earth metals | highly reactive (s2) |
| Characteristics of halogens | Non-metals; (p5) |
| Characteristics of Noble Gases | stable; inert (p6) |
| Characteristics of transition block | (d) block; metals; unfilled electron orbitals yield colorful substances |
| Inner transition elements | (f) block; bottom of Periodic Table; Lanthanides and Actinides |
| Def: Ionization Energy | amount of energy required to lose one valence electron and become an ion |
| Def: Atomic Radius | distance from farthest valence electron to the nucleus of the atom |
| Def: Electron Affinity | change in energy with gain of an electron when element is in gaseous state |
| Def: Electronegativity | measure of attraction between atoms and electrons |
| Trend of Ionization Energy | Left to Right (increases) Up to Down (decreases) |
| Largest Ionization Energy on PT | Helium (farthest right and farthest up) |
| Smallest Ionization Energy on PT | Francium (farthest left and farthest down) |
| Trend of Atomic Radius |
