Question

The most electropositive element is

• A. Cs
• B. Ga
• C. Li
• D. Pb

Answer 1

The correct option is A

Cs

1. Electropositivity increases down the group.
2. In the given options Lithium (Li) and Caesium (Cs) are the alkali metals. So that they are more electropositive than Gallium and Palladium.
3. Cesium is much more electropositive than Lithium as electropositivity increases down the group.

Hence, option(a) is correct. Caesium is the most electropositive element.
