WebAtomic Radius is a term describing the distance between an atom’s nucleus, and its outermost electron shell. Several factors affect this distance; including the number of an element, and the number of electron shells. Through Periodic trends, the atomic radius increases in size further left of a period, and lower down a group.

Ionic Radius Trends in Modern Periodic Table - Vedantu

WebThis page explores the trends in some atomic and physical properties of the Group 7 elements (the halogens) - fluorine, chlorine, bromine and iodine. You will find separate sections below covering the trends in atomic radius, electronegativity, electron affinity, melting and boiling points, and solubility. There is also a section on the bond ... WebWhen an atom loses an electron it forms a cation and when it gains an electron it becomes an anion. The Ionic radius can be described as the distance between the nucleus of an ion and the outermost shell of the ion. The atomic size of a cation will be smaller than that of the parent atom. An anion is relatively larger in size than its parent atom. WebExplaining the trend. The trend is explained in exactly the same way as the trend in atomic radii. As you go across the period, the bonding electrons are always in the same level - the 3-level. They are always being screened by the same inner electrons. All that differs is the number of protons in the nucleus. taiwan ethnic composition
