Li2 is formed by two Li atoms
-
The 2s orbitals interact to give a bonding orbital and an antibonding
orbital
-
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
