The water molecule h2o is polar because it contains two polar single bonds and a. its molecule has a linear shape. b. molecules that contain polar bonds are always polar. c. its molecule has a bent shape. d. the attractions between water molecules are strong.

Option (C) is the correct answer.

Explanation:

Water is a polar molecule because it has two polar single bonds and also it has bent shape structure.

Since the oxygen atom of water has two lone pair of electrons and also dipole moment is more towards the oxygen atom. As a result, there will be increase in electron density across the oxygen atom which will induce a negative charge on oxygen and positive charge on hydrogen atom.

Thus, water molecule becomes polar in nature.

b.final

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
