Solution.

The effective charge of the nucleus Qeff is the charge that acts on the selected electron from the side of the nucleus. The greater the effective charge of the nucleus, the electron attracting, the more the electron's energy decreases when it goes from the outside to the orbital of the atom.The ionization potential is smaller, the smaller the effective charge of the nucleus, and the larger the average electron distribution radius.
