The electronic configuration of carbon and boron are as follows:
C: 1S2,2s2, 2px1,2py1
B: 2S2, 2s2,
2px1
Due to higher nuclear charge in carbon, the force of attraction towards
valency electron is more in carbon atom and hence the first ionization energy
is greater than boron atom. After loss of one electron, the mono-valent cations
have the configurations as follows:
C: 1S2 ,2s2 2px1,
B: 2S2 , 2s2,
Configuration of B+ is stable one and hence the removal of electron is
difficult in comparison to C+. Hence, second ionization potential of boron is
higher than carbon.
