Answer
- Monoatomic are inert gases that do not combine and exist as monoatomic gases
- Diatomic- (a) 2- diatomic- NO2 = 1+ 2 = 3., HCl = 1+ 1 = 2
- Triatomic-N2O = 2 + 1 = 3., NO2 = 1+ 2 = 3, O3 = 3
- Tetraatomic- H2O2 = 2 + 2 = 4, P4O10 = 4 + 10 = 14, P4 = 4, CH4 = 1+ 4= 5
- Octa atomic- C2H6 = 2 + 6 = 8
