Ionization energy of beryllium is greater than the ionization energy of boron. Why? |
|
Answer» Solution :`Be (Z =4) 1s^2 2s^2`. It has completely filled valence electrons, which requires HIGH `IE_1`. `B (Z =5) 1s^2 2s^2 2p^`. It has INCOMPLETELY filled valence electrons, which requires comparatively less `IE_1`. Hence `I.E_1. Begt I.E_1 B`. |
