The crystal structure of an ionic compound depends on the . a) sizes of cations and anions. b) ratio of cations to anions. c) masses of cations and anion. d) both a and b

The crystal structure of an ionic compound depends on the sizes of cations and anions, as well as the ratio of cations to anions. The ratio of the cations and anions need to be even, otherwise, the crystal won't form.

So the answer would be D, both A and B.

D) Both a and b

First let's understand;

What is crystal structure?

A crystal consists of atoms, molecules or ions arranged in a highly ordered microscopic structure.
These materials are held collectively through interatomic forces (chemical bonds) along with metal bonds, ionic bonds, covalent bonds, van der Waals bonds, and others.

The crystal structure of an ionic compound is held together by electrostatic attractions.

For example: Potassium fluoride(KF)

Factors on which the crystal structure of an ionic compound depends are:

The relative sizes of the ions and
The ratio of the numbers of positive and negative ions in the compound.
