Question

Arrange the following according to the increasing electronegativity.
1. Al, Mg, Na, Si 2. Rn, Ar, Xe, Kr 3. In, Sr, Rb, Sn

Answer 1

Electronegativity increases as we go from left to right along the periodic table and decreases when we move from top to bottom of the periodic table.

Hence, the answers are as follows:-

1. Na < Mg < Al < Si

2. Rn < Xe < Kr < Ar

3. Rb < Sr < In < Sn
