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)
