Ans: Formation of N2 molecule: Electronic Configuration
σ1s2 σ* < 1s2 < σ2s2 < σ*2s2 < [ π2p2x = π2p2y] < σ2p2z
The bond order will be:
( 10-4)= 3.0
Bond order indicates the number of bonds in a diatomic molecule. Triple bond N=N.
Formation of F2 molecule: Electronic Configuration
σ1s2 < σ*1s2< σ2s2 < σ*2s2 < σ2p2z < [ π2p2x = π2p2y] < [ π*2p2x = π*2p2y] σ*2p2z
The bond order will be:
( 10-10)= 0
Hence there will be no bond formation in between the neon atoms.

He2 has zero bond order hence it does not exist.
The three fundamental laws of chemistry are - Law of Definite Proportions, Law of Conservation of Mass, and Law of Multiple Proportions.
The three types of chemical bonds are - ionic, metallic and covalent bonds. When the electrons transfer between the atoms, they form the Ionic bonds by producing charged ions that are attracted to each other. When atoms share electrons, covalent bonds are created. When metal atoms share a sea of delocalized electrons, metallic bonds get created.
