Using the periodic table, complete the following. Element: oxygen symbol: 02 Molecular weight: 32gMass of one mole: 32g g/mol

Explanation:

Oxygen

It is placed in group 16 and period 2 rd .Its atomic number is = 8No. of protons = 8No. of electrons =8 Electronic configuration=2,6Valence shell =  LValence electron = 6valency =-2Its 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 .

They carry out the exchange of gases as we breathe ( oxygen and carbon dioxide).
