WebIt's saying that the effective nuclear charge of Lithium and Hydrogen are BOTH +1, even though Lithium has +2 more protons than Hydrogen. He was illustrating that while both atoms have a effective nuclear charge of +1, the ionization energy of Lithium is much lower. This is due to the distance of the valence electrons from the nucleus (further ... WebThis is due to increasing principle quantum number, n, and the increase in effective nuclear charge, Zeff, across a period. The increasing effective nuclear charge steadily draws the valence electrons closer to the nucleus, causing the bonding atomic radius to decrease.
