Explanation The electron configuration of Ne having atomic number 10 is 1s 2 2 s 2 2 p 6 . Therefore, the total number of electrons present in Ne 2 molecule are 20 . Therefore, the electronic configuration of Ne 2 molecule is, ( σ 1s ) 2 ( σ 1 s ∗ ) 2 ( σ 2s ) 2 ( σ 2s ∗ ) 2 ( σ 2p z ) 2 ( π 2 p x ) 2 ( π 2 p y ) 2 ( π 2 p x ∗ ) 2 ( π 2 p y ∗ ) 2 ( σ 2p z ∗ ) 2 The bond order of Ne 2 is calculated by the formula, Bond order = 1 2 ( N b − N a ) Where, N b is the number of electrons present in bonding molecular orbital. N a is the number of electrons present in anti bonding molecular orbital. Substitute the value of 10 for N b and 10 for N a in the above formula as it has 10 electron in the bonding MO and 10 electrons in the antibonding molecular orbital. Bond order = 1 2 ( 10 − 10 ) = 0 Therefore, the bond order of Ne 2 molecule is 0 . The electron configuration of N having atomic number 7 is 1s 2 2 s 2 2 p 3 . Therefore, the total number of electrons present in N 2 + ion are 13 . Therefore, the electronic configuration of N 2 + molecule is, ( σ 1s ) 2 ( σ 1 s ∗ ) 2 ( σ 2s ) 2 ( σ 2s ∗ ) 2 ( π 2 p x ) 2 ( π 2 p y ) 2 ( σ 2p z ) 1 Therefore, the bond order of N 2 + ion is calculated by the formula, Bond order = 1 2 ( N b − N a ) Where, N b is the number of electrons present in bonding molecular orbital. N a is the number of electrons present in anti bonding molecular orbital. Substitute the value of 9 for N b and 4 for N a in the above formula as it has 9 electron in the bonding MO and 4 electrons in the antibonding molecular orbital. Bond order = 1 2 ( 9 − 4 ) = 5 2 = 2.5 Therefore, the bond order of N 2 + ion is 2.5 . The electron configuration of B having atomic number 5 is 1s 2 2 s 2 2 p 1 . Therefore, the total number of electrons present in B 2 molecule are 10 . Therefore, the electronic configuration of B 2 molecule is, ( σ 1s ) 2 ( σ 1 s ∗ ) 2 ( σ 2s ) 2 ( σ 2s ∗ ) 2 ( π 2 p x ) 1 ( π 2 p y ) 1 Therefore, the bond order of B 2 is calculated by the formula, Bond order = 1 2 ( N b − N a ) Where, N b is the number of electrons present in bonding molecular orbital
