Mnemonic for Valency (1–20 Elements)
| Element | Symbol | Valency | Tip/Mnemonic |
|---|---|---|---|
| H | H | 1 | Hydrogen bonds once → H₂O |
| He | He | 0 | Noble gases are stable |
| Li | Li | 1 | Group 1 metal |
| Be | Be | 2 | Think "Be = 2e" |
| B | B | 3 | Boron = 3 bonds (often forms BF₃) |
| C | C | 4 | Carbon has 4 arms → CH₄ |
| N | N | 3 | Forms NH₃ |
| O | O | 2 | Think of H₂O |
| F | F | 1 | Forms HF |
| Ne | Ne | 0 | Inert like other noble gases |
After that, valency repeats or depends on oxidation state. For ease, Group 1 = 1, Group 2 = 2, Group 13 = 3, Group 14 = 4, etc.
Quick Trick for Common Groups:
- Group 1 (Alkali Metals): Always 1 valency → Li, Na, K
- Group 2 (Alkaline Earth): Always 2 → Be, Mg, Ca
- Group 13: 3 → B, Al
- Group 14: 4 → C, Si
- Group 17 (Halogens): 1 → F, Cl
- Group 18 (Noble gases): 0 (stable)
