The Central atom has no lone pairs in CH4
Methane (CH4) does not have any lone pairs of electrons on the central carbon atom. All electrons are involved in bonding with the four hydrogen atoms, resulting in a tetrahedral geometry.
There are four pairs of electrons around the central carbon atom of methane. These pairs each consist of one electron originally from the carbon and one from the hydrogen atom bonded to it.Though the question only considers the outer shell of electrons, as that is the only shell used for bonding, it may be useful to remember that in methane the carbon atom has a total of ten electrons around it, due to its two inner electrons.
Each carbon atom in carbon monoxide has 2 lone pairs of electrons assigned to it.
There are 2 lone pairs in each Oxygen atom. So there are 4 lone pairs in total, which means 8 lone pair electrons.
NONE!!! Each bonding electron in carbon is paired with the bonding electron in each of the four hydrogens. So there are no lone pairs.
There is one lone pair of electrons on the central nitrogen atom in ammonia (NH3).
Electrons exist as pairs. Although, electrons hate each other, and only go as pairs as a last resort.
Methane (CH4) does not have any lone pairs of electrons on the central carbon atom. All electrons are involved in bonding with the four hydrogen atoms, resulting in a tetrahedral geometry.
In carbon monoxide (CO), there are no unshared pairs of electrons. All the electrons are involved in bonding between carbon and oxygen.

1molecule of C2H6 contains 2 carbon atoms
Each iodine atom in a molecule of carbon tetraiodide has three non-bonding pairs of electrons.
a carbon atom can share electrons with up to four other atoms.
The difference in bond angles between carbon dioxide and water is caused by the arrangement of the atoms and the presence of lone pairs of electrons. In carbon dioxide, the molecule is linear with a bond angle of 180 degrees because there are no lone pairs on the central carbon atom. In water, the molecule is bent with a bond angle of about 104.5 degrees due to the presence of two lone pairs on the central oxygen atom, which repel the bonded pairs and compress the bond angle.
