Explanation:

Oxygen

It is placed in group 16 and period 2 rd. Its atomic number is = 8 No. of protons = 8 No. of electrons = 8 Electronic configuration=2,6 Valence shell = L Valence electron = 6 valency = -2 Its isotopes are O-16, O-17, O-18 It exist as diatomic gas (O₂) Its atomic mass is = 16g Its molecular mass = 16 x 2 = 32g It is supporter of combustion. It is necessary for survival.
