Question

Explain how a covalent bond is different than an ionic bond. Give examples of molecules that are formed by each type of bond.

Answer 1

Ionic bond

Ionic Bond-NaCl

Covalent bond-

Step-by-step explanation:

Covalent bond is formed by sharing of electrons between two non metals to complete their octet.The covalent bond is formed between two non metals which have similar electronegativity.

While ionic bond is formed by gain or lose of electrons between metal and non metal and complete their octet.It is formed between two ions in which one is positive due to lose of electrons and other non metal is negative ion due to gain of electron.

Ionic bond is formed by lose or gain of electrons therefore, it is stronger than covalent bond.

Example of ionic bond is NaCl

Example of covalent bond is Ch4

these two opposite ions attract each other and form the ionic bond while Covalent bond is a form of chemical bonding between two nonmetallic atoms which share pairs of elctrons.

Answer 2

Explanation - The covalent bond is formed when two atoms are able to share electrons whereas the ionic bond is formed when the "sharing" is so unequal that an electron from atom A is completely lost to atom B, resulting in a pair of ions.
