Question

DATE: the first ionization enthalpy of the boron is less than the berellium give the reason are why​

Answer 1

Answer:

Because

Berellium Be is 1s²2s²

and Boron (B) is 1s²2s²2p¹

as s orbital is closes bounded to the nucleas of the atom more than p orbital.

energy required to ionization of Boron will be easier as enthalpy will be less compared to ionizing Berellium which has more stable structure and strongly bounded electrons in S orbit.
