Write the molecular orbital electronic configuration of helium, lithium, hydrogen, C₂, N₂, O₂, and F2. Calculate the bond order and predict the magnitude of each species.
a) Helium: (1s²)
b) Lithium: (1s²2s)
c) Hydrogen: (1s¹)
d) (C₂): (σ₁s²σ1s²2σ₂s²σ2s²2π₂p⁴)
e) (N₂): (σ₁s²σ1s²2σ₂s²σ2s²2π₂p⁴σ₂p²)
f) (O₂): (σ₁s²σ1s²2σ₂s²σ2s²2π₂p⁴σ₂p⁴)
g) (F₂): (σ₁s²σ1s²2σ₂s²σ2s²2π₂p⁴σ₂p⁴)
Bond order: ( 12(nbonding - nantibonding))
Predicted magnitude: The species with higher bond order will have stronger bonds.
