Question

calculate the bond order of He₂⁺

Open in App

Solution

As each Helium atom contains 2 electrons, the number of electrons in He₂⁺ ion will be 3. Two electrons will enter the bonding

σ(1s) molecular orbital and the third electron will enter the antibonding σ^(1s) molecular orbital. Thus electronic configuration of He₂⁺ will be:

[σ(1s)]²[σ^(1s)]¹

Here, Nb( electron in bonding orbital) = 2

Na (elelctron in antibonding orbital) = 1

Bond order = 1/2 ( Nb - Na )

bond order = 1/2 (2-1)

bond order = 1/2
