Question

define ionic compound and also write their two properties and give example​

Answer 1

An ionic compound is a compound formed by ions bonding together through electrostatic forces.

Examples: Table salt, NaCl, is an ionic compound. Another example is silver iodide, AgI.

Properites:

Although they consist of positively and negatively charged ions, ionic compounds are electrically neutral, because the charges are always equal and opposite.

In its purest form, ionic bonding is not directional. It can be regarded as simple positive-negative Coulombic attraction between point charges. This is different from covalent bonding, in which electrons are shared by atoms, forming directional bonds.
