WebThis is because the positive charge of the nucleus increases whilst the electrons remain at the same average distance, this makes it more difficult to pull an electron away from the nucleus and hence the ionization energy decreases. Ionization energy decreases down a group (ie, as you move down a column in the period table).

The effective nuclear charge is a measure of the pull exerted on the electrons by the nucleus. In essence, it relates to an increase in atomic number , i.e. the number of protons in the nucleus, that's unbalanced by an increase in atomic size.

WebThe effective nuclear charge experienced by the valence (3s) electron in the neutral sodium atom is +1. We get this number by subtracting the inner core electrons (10) from the total nuclear charge (11). After removing the 3s electron we have Na +, which has the electron configuration of 1s 2 2s 2 2p 6. The next electron removed comes from the ...
