The first (IE(1)) and the second (IE(2))...

The first (`IE_(1)`) and the second `(IE_(2))` ionisation energies (kJ `mol^(-1)`) of a few elements are given below :

Which of the above elements is likely to be
a reactive metal?

Text Solution

Verified by Experts

The element with lowest `IE_1` value is likely to be a reactive metal. Thus, element II is a reactive metal.
