Question

(c) Define ionic radii. How are the ionic
radii of ions in ionic crystals which have
isoelectronic ions determined?
​

Answer 1

Explanation:

Mass, in physics, quantitative measure of inertia, a fundamental property of all matter. It is, in effect, the resistance that a body of matter offers to a change in its speed or position upon the application of a force. The greater the mass of a body, the smaller the change produced by an applied force.

Answer 2

Answer:

In each ionic crystal the cations and anions are isoelectronic with inert gas configuration. Pauling has calculated the radii of the ions on the basis of the observed internuclear distances in four crystals namely NaF, KCl, RbBr and CsI.
