Chlorine (nucleus) has 1 lone pair and 3 polar-covalent bonding pairs (the shared pairs with O). Each oxygen (nucleus) has 3 lone pairs and 1 polar-covalent bonding pair (the shared pair with Cl)
If an atom has five valence electrons, it will have one lone pair of electrons.
2
There are 1
i pretty sure there's only 1 pair of electrons on XeF6
There are four electrons, which is two pair.
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 phosphine (PH3), there are three lone pairs and three bonding pairs.
Chlorine (nucleus) has 1 lone pair and 3 polar-covalent bonding pairs (the shared pairs with O). Each oxygen (nucleus) has 3 lone pairs and 1 polar-covalent bonding pair (the shared pair with Cl)
There are no lone pairs of electrons in a nitrogen molecule (N2) because nitrogen atoms share electrons to form a triple bond between them.
There are no lone pairs in the nitrate ion (NO3-). The nitrogen atom forms three sigma bonds with oxygen atoms, leaving no non-bonding pairs of electrons.
There are no lone pair electrons on the central carbon atom in CO2. Each oxygen atom forms a double bond with the carbon, utilizing all of its valence electrons for bonding.
There are three lone pairs present in chlorine atom
H2SO4 does not have any lone pairs. It has 2 bonding pairs shared between sulfur and oxygen in each of the O=S=O bonds. Each oxygen also has 2 unshared pairs of electrons.
In $\ce{NiCl2}$, the nickel atom typically exhibits a coordination number of 6. This means that there are no lone pairs of electrons on the nickel atom, since all of its electrons are involved in bonding with the chlorine atoms to form the complex.
There are two lone pairs of electrons on the As atom in AsCl3.
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.
