Types of Atomic Radii

Based on the type of bond, atomic radii is divided into three types as follows:

• Covalent Radius
• Ionic Radius
• Metallic Radius

Covalent Radius

The covalent radius represents the distance from the center of an atom’s nucleus to the point at which the electron cloud effectively ends, where it overlaps with another atom’s electron cloud in a covalent bond.

The covalent radius can be calculated when there is a covalent link between two atoms. Because the electrons are drawn to the same atoms equally when they are covalently bound, the radius of each atom equals half the distance between the two nuclei. An atom’s diameter can be found by measuring the distance between its two nuclei, but you want the radius, which is half the diameter.

Ionic Radius

Ionic radius refers to the size of an ion, which is an atom or group of atoms that has gained or lost electrons, resulting in a net electrical charge. An ion can be positively charged (cation) or negatively charged (anion), and its ionic radius can vary depending on the type of ion formed.

The ion with a positive charge will have a smaller size than the ion with a negative charge if we consider the charge of the ion.

Metallic Radius

Metallic radius, also known as the metallic atomic radius, refers to the size of an atom in a metallic solid or the context of metallic bonding.

The radius of an atom connected by a metallic connection is known as the metallic radius. In a metallic cluster, the metallic radius is half of the total distance between the nuclei of two neighboring atoms. Each atom in a metal will be the same distance apart since it is a collection of atoms of the same element.

Atomic Radii refer to the size of an atom, indicating how big or small an atom is. Atomic Radii or size, is defined as the shortest distance between the center of an atom’s nucleus and its outermost shell. This concept is similar to the radius of a circle, with the nucleus being analogous to the circle’s center and the outermost orbital of the electron corresponding to the circle’s outer edge. In this article, we will discuss various concepts related to atomic radii of various elements in detail.
