Your answer is D
I hope that this answer is helpful to you
can u explain?
yes definitely
first ionization potential of beryllium is greater than boron due to following configuration
(I. e) 4Be=1s²,2s² , 5B=1s²,2s²,2p¹
order of attraction of electrons towards nucleus 2s›2p
so more amount off energy is required to remove the electron with 2s-orbital when compared to 2p-orbital
I think you have understood
