Verified step by step guidance

Step 1: Determine the total number of valence electrons for the molecule NOF by adding the valence electrons of each atom: nitrogen (N), oxygen (O), and fluorine (F).

Step 2: Identify the central atom, which is usually the least electronegative element (excluding hydrogen). In this case, nitrogen (N) is the central atom.

Step 3: Arrange the atoms around the central atom and connect them with single bonds initially. Each single bond represents 2 electrons.

Step 4: Distribute the remaining valence electrons as lone pairs to satisfy the octet rule for each atom, starting with the outer atoms (O and F) and then the central atom (N).

Step 5: Check if the octet rule is satisfied for all atoms and adjust bonding (single, double bonds) and lone pairs if necessary to ensure the molecule is neutral and all atoms have complete octets.
