Question
Generally the ionization enthalpy in a period increases but there are some exceptions, the one which is not an exception is?
Answer: Option D
:
D
The ionization energy increases normally from sodium to magnesium as Mg has a higher effective nuclear charge as compared to Na.
In the case of Be and B, and N and O, Be is more stable because of its electronic configuration.
