Question

The ground state electron configuration of He 2+ is
(sigma 1s2)(sigma 1s1)Calculate the bond order of He 2+​

Answer 1

Answer:

Bond order of  is 0.5.

Formula for Bond order is :  

Where  is Number of Bonding molecular orbital Electrons, which is 2 for  

is number of anti-bonding molecular orbital electrons, which is 1 for

Hence, the Bond order is =   (2-1) which gives   as the answer.  

So, the bond order for  and  are  which is 0.5.
