Molecular consists of multiple atomic orbitals
Each carbon atom in benzene has 3 sp2 hybridized orbitals.Benzene has 6 carbon atoms.Therfore, there are 18 sp2 hybridized orbitals in benzene.
THREE ORBITALS ARE FOUND IN P-ORBITAL
Each orbital can contain a maximum of 2 electrons only different in their spin momentum: +1/2 and -1/2. The 4s orbital is fully 'used' from Ca (no.20) onward: 1s2 2s2 2p6 3s2 3p6 4s2 The 4s2...
Beryllium's electron configuration is 2s^2. It has two shells and has two electrons occupying the "s" orbital.
