Question

First ionization energy of boron is less than that of beryllium explain why

Answer 1

Answer:the ionization energy of beryllium is more than that of Boron because beryllium has a stable electronic configuration which makes it difficult to remove the valence electron from outermost shell... Whereas Boron does not have a stable electronic configuration... ( it has 1 electron in the 2p orbital).. So electron removal is easy..

Hope this helps...
