Question

Calcium chloride forms an ionic solid. how are the particles held together and arranged in the solid

Answer 1

Calcium chloride forms an ionic compound with a regularly arranged lattice of oppositely charged ions.

The Na+ and Cl- ions are held together by strong electrostatic forces. 

Hope that helps

Answer 2

Explanation:

As we known that an ionic solid is a solid whose atoms chemically combine together by transfer of electrons from one atom to another.

For example, $CaCl_{2}$ is an ionic solid because transfer of electrons take place from calcium to chlorine.

As a result, calcium atom has a partial positive change and chlorine atom has a partial negative charge. Hence, there will be strong intermolecular forces of attraction between the two because opposite charges attract each other.

Therefore, particles will be arranged in a regular crystal lattice of opposite charges.
