Being the first elements of each period, alkali metals have the largest atomic and ionic radii in their respective periods. As we move within a period, the atomic radius and ionic radius tend to decrease due to increase in the effective n..

The distance from the centre of the nucleus to the outermost shell of an atom is called the atomic radius of that atom..

The distance from the centre of the nucleus to the outermost shell of an atom is called the atomic radius of that atom (Fig. 2.1..

The radius is the lateral bone of the forearm. It is a long bone with a shaft and two extremities. It is shorter than the ulna. The upper extremity of the radius is small and shows button-shaped head with a shallow upper surface for articulation with the capitulum of the humeru..

A cation is formed by the loss of one or more electrons from the gaseous atom. Thus, the whole of the outer most shell of electrons is removed resulting in the smaller size in the cation. For example, in lithium atom, there is only one electron in the outermost '2s' shell. As t..

By Avogadro's hypothesis, the actual volume occupied by the atoms in one gram of a substance is 2/3 r d of the volume occupied by 1 gram of the substanc..

Ionic Radii - These are radii of ions in ionic crystals. Ionic radius may be defined as the effective distance from the center of nucleus of an ion up to which it has an influence on its electron cloud. In ionic compounds the inter nuclear distance ..
