Question

Why the ionization enthalpy of b is less than be​

Answer 1

Explanation:

• as we know that be (berilium) is the element with atomic number 4 and it's atomic configuration is 1s^2 2s^2.

• b(boron) is the element with atomic configuration 1s^2 2s^2 2p^1.

• hence it is easy to take out element in s-block with compare to p-block elements

so ionization enthalpy of b is less than be
