Vander Waal constant for gas molecules are given: {:("Gas",a(L^(2)"atm//"mol^(2)),b(L//"mol")),(He,0.0341,0.02370),(Ne,0.211,0.0171),(Xe,4.19,0.0510),(O_(2),1.36,0.0310):}

Answer»

He is monoatomic GAS, where as nearly all molecules that make up air are DIATOMIC eg:
`N_(2),O_(2)` etc.
Ne
Xe
`O_(2)`
