Which metal is placed highest in the reactivity series?

RRB Group D, 10-Feb-26 S-2 2026
✓ Answer: C Sodium
Sodium is placed highest among the given metals and it reacts vigorously with water and oxygen. Sodium is an alkali metal (Group 1) with one valence electron, which it 'wants' to lose urgently to become stable. However, the metal placed highest in the standard reactivity series is Potassium (K) due to very low ionization energy. Other reactive metals are Caesium, Francium, Rubidium, Lithium, Calcium, and Magnesium.
