Web8 apr. 2024 · The metallic properties increase down the group as the nuclear charge decreases down the group. Since the valence electron is loosely bounded by the nuclei, they are able to conduct electricity well. But across a period, the metallic character decreases as nuclear charge increases. In atomic physics, the effective nuclear charge is the actual amount of positive (nuclear) charge experienced by an electron in a multi-electron atom. The term "effective" is used because the shielding effect of negatively charged electrons prevent higher energy electrons from experiencing the full nuclear charge of the nucleus due to the repelling effect of inner layer. The effective nuclear charge experienced by an electron is also called the core charge. It is possible to determine the …

Why does nuclear charge decrease down the group?

Web28 sep. 2024 · For main group elements, atomic size gets larger as you go down a group (column) and atomic size gets smaller as you go across a period (row). Let’s use the following condensed periodic table to show the relative sizes of the main group elements. How atomic size trends across main group elements. Web6 nov. 2024 · What happens when nuclear charge increases? A higher effective nuclear charge causes greater attractions to the electrons, pulling the electron cloud closer to the nucleus which results in a smaller atomic radius.
