Question

Calcium lies above Sodium in the reactivity series.

• A. True
• B. False

Answer 1

The correct option is B False

1. In a reactivity series, the most reactive metal is placed at the top and the least reactive element at the bottom.
2. More reactive elements have a greater tendency to lose electrons and form positive ions.
3. Since Sodium ($\mathrm{Na}$) is more reactive than Calcium($\mathrm{Ca}$), therefore it is placed above Calcium in the reactivity series.

Therefore, the given statement- Calcium lies above Sodium in the reactivity series is false.
