Answer:

Bond order is the number of bonding electrons minus the number of antibonding electrons, "all over 2", hence, (2-0)/2 = 1. Atomic orbitals available for making Molecular Orbitals are 1s from each Helium.

Answer:

What is the bond order of He2?

In He2 molecule,

Atomic orbitals available for making Molecular Orbitals are 1s from each Helium. And total number of electrons available are 4.

Molecular Orbitals thus formed are:€1s2€*1s2

It means 2 electrons are in bonding molecular orbitals and 2 are in antibonding molecular orbitals .

Bond Order =Electrons in bonding molecular orbitals - electrons in antibonding molecular orbitals /2

Bond Order =Nb-Na/2

Bond Order =2-2/2=0

Since the bond order is zero so that He2 molecule does not exist.
