The central atom in CH4 is carbon, which has four bonding groups. Each bonding group is a hydrogen atom bonded to the central carbon atom.

There are two electron groups in CO2. Each oxygen atom is bonded to the central carbon atom through a double bond, resulting in two electron groups around the central carbon atom.
In ozone (O3), there are 2 unshared electrons and 2 bonding electrons around the central oxygen atom. Each of the terminal oxygen atoms contributes a single unshared electron, while the central oxygen atom shares a pair of electrons with each terminal oxygen atom to form the bonds.
In CH4, there are four regions of high electron density surrounding the central carbon atom. These regions correspond to the four bonding pairs of electrons in the four C-H bonds around the central carbon atom.
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.
A calcium atom has 2 electrons in its outermost shell, which are involved in chemical bonding. These electrons can be donated or shared with other atoms to form bonds.
3 bonds
3 bonding pairs and one lone pair or non-bonding pair
In ozone (O3), there are 2 unshared electrons and 2 bonding electrons around the central oxygen atom. Each of the terminal oxygen atoms contributes a single unshared electron, while the central oxygen atom shares a pair of electrons with each terminal oxygen atom to form the bonds.

The answer is 1. This is because the only atom with lone paires is phosphorus and it only has 1.
Each iodine atom in a molecule of carbon tetraiodide has three non-bonding pairs of electrons.
you have 5 binded elektron pairs, and one free pair
SF6 has no lone pairs on the central atom sulfur. It forms six bonds with fluorine atoms which gives it an octahedral geometry.
IN an ammonia molecule the central nitrogen atom has 3 three bonds.
it will form three bonding
In an ammonia molecule (NH3), there is one nonbonding pair of electrons on the nitrogen atom.
Each potassium atom has one valence electron available for bonding.
