How does nuclear charge change down a group

WebElectropositive nature of an element increases down the group because the effective nuclear charge decreases and the atomic size increases down the group, so because of the addition of new shells to the atom the attraction of the valence electrons to the nucleus decreases due to large distance between them . WebMay 1, 2024 · According to Coulomb's law, the attraction of an electron to a nucleus depends only on three factors: the charge of the nucleus (+Z), the charge of the electron ( …

WebJun 12, 2024 · Now why does it decrease down a group? Well, even though there's a noticeable increase in nuclear charge, there's even an increase in distance from nucleus and in shielding effect. This is clear because when you descend down a group, a new principal quantum shell is occupied by valence electrons. WebJan 30, 2024 · The increased nuclear charge as you go down the group is offset by extra screening electrons. Each outer electron in effect feels a pull of 7+ from the center of the atom, irrespective of which element you are talking about.
