Expert Answer

Step 1

In a molecule or compound, two or more atoms combined together by bonds called chemical bonds or atomic bonds. There are two types of bonds, namely ionic bonds, and covalent bonds.

Step 2

Ionic bonds are formed when an atom donates its electrons to the other atom for stabilization.  Atoms having different electronegativity values participates in an ionic bond. That is, the atoms which are weakly electronegative can easily share electrons with atoms that are strongly electronegative.

Ionic bonds are formed between a metal and non-metal. Metal donates its electron to non-metal. Ionic compounds dissociate into ions in water.

Step 3

Example: NaCl

                 Sodium and chloride are oppositely charged molecules and when they combine, the sodium atom loses an electron and become cation (Na+) and the chlori...
