Question

consider the molecule f₂. part: 0 / 2 part 1 of 2 draw the mo diagram for the molecule. be sure your diagram contains all of the electrons in the species, including any core electrons.

Explanation:

Step1: Determine number of electrons

Fluorine has atomic number 9, so F₂ has 9×2 = 18 electrons.

Step2: Fill molecular - orbital levels

Start filling the molecular - orbital levels in order of increasing energy. The order of filling for homonuclear diatomic molecules is σ1s, σ1s, σ2s, σ2s, σ2p, π2p, π2p, σ2p. Fill the orbitals with electrons following the Pauli - exclusion principle and Hund's rule.

• σ1s: 2 electrons
• σ*1s: 2 electrons
• σ2s: 2 electrons
• σ*2s: 2 electrons
• σ2p: 2 electrons
• π2p: 4 electrons
• π*2p: 4 electrons
• σ*2p: 0 electrons

To draw the MO diagram:

1. Draw a vertical axis labeled "Energy".
2. On the left - hand side, label two columns as "Atomic Orbitals of F" and on the right - hand side as "Molecular Orbitals of F₂".
3. Draw the 1s, 2s, and 2p atomic orbitals for each F atom on the left - hand side.
4. Draw the molecular orbitals (σ1s, σ1s, σ2s, σ2s, σ2p, π2p, π2p, σ2p) in the middle in order of increasing energy.
5. Fill the molecular orbitals with the 18 electrons as described above.

Since this is a drawing task and not possible to directly provide a drawn diagram in this text - based format, the steps above describe how to construct the MO diagram for F₂.

Answer:

Follow the steps above to draw the MO diagram for F₂ with 18 electrons filled in the molecular orbitals in the correct order of energy.
