Ever wondered about the term ionic radii? In this article, we will explore what ionic radii are and how they vary across the groups and periods of the modern periodic table .

Atomic radius is the mean or typical distance from the centre of the nucleus to the boundary of the surrounding shells of electrons.
Define ionic radius.
Ionic radius is the distance from the nucleus of an ion up to which it has an influence on its electron cloud.
Define cation and anion.
When an atom loses an electron it forms a cation and when it gains an electron it becomes an anion.
What are isoelectronic species?
Atoms and ions which consist of an equal number of electrons are considered electronic species.
Why the size of the anion is larger than the parent atom?
An anion is relatively larger in size than its parent atom. This is because when an atom gains electrons the total number of electrons increases which tends to create more repulsion between electrons and thus overshadows the net effective nuclear charge.
