Answer 1

Ionic Radi:-

Ionic radius, rion, is the radius of a monatomic ion in an ionic crystal structure.

Factors Affecting:-

These Factors are:

• The number of protons in the nucleus (called the nuclear charge).

• The number of energy levels holding electrons (and the number of electrons in the outer energy level).

• The number of electrons held between the nucleus and its outermost electrons (called the shielding effect).
