Which among the following elements has highest electronegativity?

Which among the following elements has highest electronegativity?
  1. K
  2. Na
  3. Li
  4. Cs

Solution

The electronegativity of Group 1 elements decreases down the group. Hence, the decreasing order of electronegativity is $\mathrm{Li}\gt\mathrm{Na}\gt\mathrm{K}\gt\mathrm{Cs}$.
