Question

Arrange the elements Se,Cl,S in increasing order of their I.E. In detail??

Answer 1

Answer:

Explanation:

The ionization energy increases across a period but decreases down a group.

The order is Sn<S<Cl

This means that the elements with the lowest ionization energies would be in the bottom left-hand corner of the periodic table. The change in ionization energies is also bigger going down the periodic table (by change within a group) than going across the periodic table (by change within a period).

Hope this helps U !
