Li2 is formed by two Li atoms
The 2s orbitals interact to give a bonding orbital and an antibonding
The configuration of Li2is Li2 1s)2(σ*1s)22s)2
Inner shell molecular orbitals (σ1s)2(σ*1s)2
These electrons do not have a significant effect on bonding
Outer shell configuration
Li2 (σ2s)2
The bond order is 1
Lewis Concept of Acids and bases
A lewis acid is a species that can form a covalent bond by accepting an
electron pair from another species
A lewis base is a species that can form a covalent bond by donating an
electron pair to another species
