We are being asked to look at the Lewis structure of HF and locate the non-bonding electrons.
First, we will have to draw the Lewis Structure of HF
Step 1: Determine the central atom in this molecule.
• With only two atoms in the molecule, there is no central atom.
Step 2: Calculate the total number of valence electrons present.
Group Valence Electrons
H 1A 1 × 1 e– = 1 e–
F 7A 1 × 7 e– = 7 e–
Total: 8 valence e–
Step 3: Draw the Lewis Structure for the molecule
Look at the Lewis structure for HF. Where are the nonbonding electrons?
