Question

Discuss the trend in the following in case of groups 16, 17 and 18 elements.

Ionization enthalpy

Answer 1

1. The elements of groups 16, 17 and 18 have a high ionization enthalpy.
2. In groups, 16, 17 and 18 the ionization enthalpy decreases down the group due to increase in atomic size, in the same order.
