Answer 1

Answer:

Na < K < Rb < Cs

Explanation:

This is because reducing capacity increases down the group.

Hope it helps, please mark my answer brainliest

Answer 2

Na < K < Rb < Cs

Explanation:

1.Reduction is a chemical reaction that involves the gaining of electrons by one of the atoms involved in the reaction between two chemicals. The term refers to the element that accepts electrons, as the oxidation state of the element that gains electrons is lowered.

2.As the size of the element E down the group increases and thus the bond dissociation energy decreases. This facilitates the dissociation of Hydrogen atoms and hence down the group, thus the reducing character increases.
