A phosphorus atom has one nonbonding pair of electrons.
1 pair. which means 2 nonbonding electrons.
In the Lewis structure of CH2Br2, carbon is the central atom with hydrogen atoms on one side and two bromine atoms on the other. There are no nonbonding electrons on the central carbon atom. Each hydrogen atom contributes 1 nonbonding electron, and each bromine atom contributes 3 nonbonding electrons, resulting in a total of 8 nonbonding electrons in the molecule.
There are two pairs of nonbonding electrons in a chloroform molecule. Each chlorine atom contributes one nonbonding pair of electrons, resulting in a total of two pairs of nonbonding electrons in the chloroform molecule.
In HF, there is one nonbonding electron on the fluorine atom. Hydrogen only has one electron, which is used for bonding with fluorine.
CO2 does not have unshared pairs of electrons.
The central atom in NH2Cl is nitrogen. Nitrogen has 2 nonbonding electron pairs.
The shape of a molecule only describes the arrangement of bonds around a central atom. The arrangement of electron pairs describes how both the bonding and nonbonding electron pair are arranged. For example, in its molecular shape, a water molecule is describes as bent, with two hydrogen atoms bonded to an oxygen atom. However, the arrangement of electron pairs around the oxygen atom is tetrahedral as there are two bonding pairs (shared with the hydrogen) and also two nonbonding pairs.
There are two pairs of nonbonding electrons in a carbonate ion, CO32-. Each oxygen atom has two lone pairs of electrons, while the carbon atom does not have any nonbonding electrons in the ion.

Ammonia (NH3) has one lone pair of nonbonding electrons on the nitrogen atom.
In HF, there is one nonbonding electron on the fluorine atom. Hydrogen only has one electron, which is used for bonding with fluorine.
CO2 does not have unshared pairs of electrons.
There is one electron in hydrogen. And since there is only one, it is obviously unpaired.
There are 5 electrons in the outermost electron shell of a phosphorus atom. Phosphorus has an electron configuration of 2, 8, 5.
The VSEPR (Valence Shell Electron Pair Repulsion) model explains molecular geometry based on the repulsion between electron pairs in the valence shell of an atom. It is mainly used because it is simple, intuitive, and provides a good approximation of molecular shapes based on the number of bonding and nonbonding electron pairs around a central atom.
