3 non bonding pairs. Fluorine is in group 17 and has an outer shell configuration of 2s2, 2p5. Just one electron in the fluorine atom is unpaired the other 6 are paired
An HCl molecule contains 3 nonbonding pairs..
Only one Lewis structure is necessary to describe the bonding in SF2. Sulfur will be the central atom, with one fluorine atom on each side of sulfur, each forming a single bond. The sulfur atom will have two lone pairs of electrons to complete its octet.
In BF3, there are 3 bonding electron pairs and 0 non-bonding electron pairs. Boron has 3 valence electrons, and each fluorine contributes one electron for bonding, giving a total of 3 bonding pairs in the molecule.
Methyl fluoride (CH3F) has three bonding pairs of electrons between carbon and hydrogen atoms in the methyl group, and one bonding pair of electrons between carbon and fluorine atoms. Therefore, there are a total of four bonding pairs of electrons in methyl fluoride.
In HF, there is one nonbonding electron on the fluorine atom. Hydrogen only has one electron, which is used for bonding with fluorine.
The Lewis structure of PF3 shows that the central phosphorus atom has one non-bonding electron pair and three bonding electron pairs. Phosphorus has five valence electrons, and in PF3, one is non-bonding while the other three are shared in bonds with the fluorine atoms.
Each iodine atom in a molecule of carbon tetraiodide has three non-bonding pairs of electrons.
CH3CFO has a total of 10 electron pairs. This includes 4 pairs from carbon (3 bonds and 1 non-bonding pair), 4 pairs from fluorine, and 2 pairs from oxygen.

Methyl fluoride (CH3F) has three bonding pairs of electrons between carbon and hydrogen atoms in the methyl group, and one bonding pair of electrons between carbon and fluorine atoms. Therefore, there are a total of four bonding pairs of electrons in methyl fluoride.
In ClF3, there are two lone pairs of electrons on the central chlorine atom in addition to the three bonding pairs with fluorine atoms. This makes a total of five valence electrons not involved in bond formation.
In GeCl4 (germanium tetrachloride), there are four bonding pairs of electrons. Each chlorine atom forms a single covalent bond with germanium to satisfy its octet.
In HF, there is one nonbonding electron on the fluorine atom. Hydrogen only has one electron, which is used for bonding with fluorine.
In NF3, the Nitrogen atom has 5 valence electrons and each Fluorine atom shares 1 more electron with Nitrogen. That makes 8 electrons (4 pairs of electrons) around Nitrogen. Betweent the four electron pairs, 3 pairs are bonded with Fluorine and the other one is a lone pair. Therefore around the central atom Nitrogen, there are three Fluorine atoms and a lone electron pair.
There are two non-bonding pairs of electrons in Cl4. Each chlorine atom in Cl4 has 7 valence electrons, forming single covalent bonds with the other chlorine atoms, leaving two lone pairs on each chlorine atom.
