Question

what is ionic radii​

Answer 1

Answer:

Ionic radius, rᵢₒₙ, is the radius of a monatomic ion in an ionic crystal structure. Although neither atoms nor ions have sharp boundaries, they are sometimes treated as if they were hard spheres

Answer 2

Answer:

The ionic radius is the distance between the nucleus and the electron in the outermost shell of an ion. ... When an electron is added to an atom, forming an anion, the added electron repels other electrons, resulting in an increase in the size of the atom.
