and shiny? *

Answer 1

Answer:

See Explanation

Explanation:

Ionic compounds are composed of crystals. The crystal structure of an ionic compound is responsible for its hardness.

A crystalline solid contains a well organized structure which enables it to be hard and have a particular geometric shape as well defined melting point.

Hence, all the observed characteristics of NaCl are the result of its crystalline structure.
