2 electron groups are in CO2. Proof, I got it wrong on a quiz. :(
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
10 because there are 20 Valence Electrons that are pairing up.
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.

The answer is 1. This is because the only atom with lone paires is phosphorus and it only has 1.
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.
there are 5 charge clouds found around the central atom in SCl4
In carbon tetrabromide (CBr₄), the central atom is carbon. Carbon has four valence electrons and forms four single bonds with the four bromine atoms, using all its valence electrons in bonding. Therefore, there are no lone pairs of electrons around the central carbon atom in CBr₄.
The central atom in the carbonate ion (CO₃²⁻) is carbon. It is surrounded by three electron domains: one for each of the three bonding pairs of electrons with oxygen atoms. These three domains are arranged in a trigonal planar geometry, with no lone pairs on the carbon atom.
There are three bonding groups found in PCl3, which consist of three P-Cl bonds.
Each potassium atom has one valence electron available for bonding.
