To determine bonding and nonbonding electrons, first draw the Lewis structure of the molecule, which represents the arrangement of atoms and their valence electrons. Bonding electrons are those that are involved in covalent bonds, typically shown as shared pairs of dots or lines between atoms. Nonbonding electrons, or lone pairs, are the valence electrons that are not involved in bonding and are typically represented as unshared pairs of dots around an atom. By counting the shared pairs and the lone pairs, you can distinguish between bonding and nonbonding electrons.
In chlorine dioxide (ClO2), the chlorine atom is bonded to two oxygen atoms and has one lone pair of electrons. The total number of unshared (or lone pair) electrons in ClO2 is 2, which come from the lone pair on the chlorine. Additionally, each oxygen atom has two lone pairs, but since the question specifically asks about unshared electrons on chlorine, the answer is 2.
A molecule with a central atom surrounded by three single bond pairs and one unshared pair of electrons would have a trigonal pyramidal geometry. This arrangement results from the repulsion between the bonding pairs and the lone pair, leading to a shape that is similar to tetrahedral but slightly distorted due to the presence of the lone pair. An example of such a molecule is ammonia (NH₃).
NH3
The central atom in NH2Cl is nitrogen. Nitrogen has 2 nonbonding electron pairs.
A nonbonding pair of electrons in the valence shell of an atom is called a lone pair or nonbonding pair of electrons. These electrons are not involved in forming chemical bonds with other atoms but still influence the atom's shape and reactivity.
CO2 does not have unshared pairs of electrons.
A phosphorus atom has one nonbonding pair of electrons.
1 pair. which means 2 nonbonding electrons.
Ammonia (NH3) has one lone pair of nonbonding electrons on the nitrogen atom.
The nitrogen atom in ammonia has one unshared pair of electrons.
they are the same. Lone pair is unshared pair of electrons and bond pair is shared pair of electron.
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.

The molecular geometry of H3O+ is Trigonal Pyramidal because it has 3 bonding pairs and 1 nonbonding pair (lone pair)
