Explain the deviation in ionsation enthalpy of some elements from the general trend by using given figure.

Text Solution

Verified by Experts

The correct Answer is:
A
There is deviation of ionisation enthalpy of some elements from the general trend as shown in figure. The first ionisation enthalpy of B is lower than that of Be and in case of nitrogen, the first ionisation enthalpy is higher than that of O.
