Question

Define : a. Ionic radius

b. Electronegativity​

Answer 1

Answer:

A) 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 treated as if they were hard spheres with radii such that the sum of ionic radii of the cation and anion gives the distance between the ions in a crystal lattice.

Explanation:

The ionic radius (plural: ionic radii) is the measure of an atom's ion in a crystal lattice. Electronegativity is the property of an atom which increases with its tendency to attract the electrons of a bond.
