Effective nuclear charge calculator
WebLet's calculate the effective nuclear charge for both of these, and first, we'll start with lithium. So for lithium, lithium has a plus three charge in the nucleus, so the effective … WebAug 30, 2024 · The effective nuclear charge holding a 2s electron to the nucleus is thus nearly +2, about twice the value for lithium, and the 2s electron clouds are drawn closer to the center of the atom. ... This means that the 2p x electron cloud is more effectively screened by the 1s electrons from the nuclear charge.
