Which of the alkali metal is having least melting point ? 1. Na 2. K 3. Rb 4. Cs

Text Solution

Verified by Experts

As the atomic size of the metal increases, the strength of metallic bonding decreases and consequently, the melting point decreases. Since the size of cesium atom is the largest, it has the least melting point.
