Question

explain why the first ionisatin energy of boron is less than that of Be?​

Answer 1

first ionisation energy of boron is less then Be because Be is stable (duplate) and nuclear force of outer electron have more but in boron the less amount of energy is required to relese a electron from outermost cell due to less nuclear force on outer electron

Answer 2

hello dear this is your answer

Energy of boron is less then Be because Be is stable but boron has less amount of energy to release a electron  from it shell
