Atomic Size [Radius]

Topic Content:

The radius of an atom is the distance between the centre of the nucleus and the outermost electronic shell. Two types of atomic radii are the covalent radius and Van der Waals radius. A covalent radius is half the distance between two identical atoms which are covalently bonded. Van der Waals radius radius is half the distance of two identical atoms which are not chemically bonded.

For example, the distance
