Question

what are lone pair and bond pair of electron ?​

Answer 1

$\huge\underline{\overline{\mid{\bold{\pink{ANSWER}}{\mid}}}}$

$\blue \implies$The electron pair being shared by the atoms is called a bonding pair ; the other three pairs of electrons on each chlorine atom are called lone pairs.Lone pairs are not involved in covalentbonding.

Answer 2

Answer:

• A bonding pair of electrons is shared between two different atoms

• The pair of electrons left in the outermost valence shell without forming covalent bonds are known as lone pairs of electrons. Example: Water molecule has two lone pairs of electrons.

• The electron pair being shared by the atoms is called a bonding pair ; the other three pairs of electrons on each chlorine atom are called lone pairs. Lone pairs are not involved in covalent bonding.
