What is the number of electrons in bonding molecular orbitals and antibonding molecular orbitals respectively in F ₂ molecule?

Step-by-step solution

The total number of electrons in the F₂ molecule is 9 + 9 = 18 . The molecular orbital electronic configuration of F₂ is: _ 1s ^2 _ 1s ^ *2 _ 2s ^2 _ 2s ^ *2 _ 2p_z ^2 _ 2p_x ^2 _ 2p_y ^2 _ 2p_x ^ *2 _ 2p_y ^ *2 The number of electrons in bonding molecular orbitals ( N_b ) is the sum of electrons in _ 1s , _ 2s , _ 2p_z , _ 2p_x , and _ 2p_y orbitals: N_b = 2 + 2 + 2 + 2 + 2 = 10 The number of electrons in antibonding molecular orbitals ( N_a ) is the sum of electrons in _ 1s ^ * , _ 2s ^ * , _ 2p_x ^ * , and _ 2p_
