Question

Read the following sentence and answer the questions:

"NaCl is an ionic compound."

1. Why is NaCl an ionic compound?
2. State any two properties of ionic compounds.

Answer 1

1. Chlorine has an electrical configuration of 2, 8, and 7, while sodium has a configuration of 2, 8, and 1. For stability, the sodium atom gives one of its electrons to chlorine, which then accepts it, resulting in the production of sodium chloride compounds. It is an ionic compound because sodium chloride is created by the exchange of electrons between the components.
2. Two properties of ionic compounds:
   1. Ionic compounds have high melting as well as boiling points.
   2. They are Good Insulators, hard and brittle in nature.
