In the Lewis structure of CHI₃ (iodoform), the central carbon atom is bonded to one hydrogen atom and three iodine atoms. The carbon atom has no unbonded electrons, while each iodine atom has three unbonded pairs of electrons. Therefore, there are a total of 9 unbonded electrons from the three iodine atoms in CHI₃.
In the molecule ONF (oxygen monofluoride), there are two unbonded electrons. The oxygen atom has six valence electrons, and it forms one bond with nitrogen and one bond with fluorine, resulting in two unbonded electrons on the oxygen. The nitrogen and fluorine atoms are each bonded to oxygen and do not have any unbonded electrons in this specific arrangement.
The s electrons in N2 are unbonded; there are four of them in each nitrogen atom and therefore 8 in the molecule N2.
Aluminum has no lone pairs of electrons in its ground state. It has three valence electrons, which it typically uses to form bonds, resulting in a stable configuration without any unbonded pairs. In compounds, aluminum often forms three bonds, such as in aluminum chloride (AlCl3), where it adopts a trigonal planar geometry.
there is only 1 lone pair present in BrF5 there are 7 electrons in Br valence shell from which 5 electrons went to make bond with F, while the remaining two makes a lone pair. and thus anly 1 lone pair exist in BrF5
There are two unbonded electrons present in SeO3^2-.
The water molecule has two pairs of unbonded electrons, also known as lone pairs. These lone pairs are located on the oxygen atom.
In the Lewis structure of CHI₃ (iodoform), the central carbon atom is bonded to one hydrogen atom and three iodine atoms. The carbon atom has no unbonded electrons, while each iodine atom has three unbonded pairs of electrons. Therefore, there are a total of 9 unbonded electrons from the three iodine atoms in CHI₃.

There are 3 pairs of valence electrons present on the boron atom in BF3. Boron has 3 valence electrons, and each fluorine atom provides one additional electron, giving a total of 6 valence electrons on boron.

there are three N-H bonds in ammonia and hence ammonia has three bonded pairs of electrons in addition, there is one lone pair of electrons on nitrogen
there is only 1 lone pair present in BrF5 there are 7 electrons in Br valence shell from which 5 electrons went to make bond with F, while the remaining two makes a lone pair. and thus anly 1 lone pair exist in BrF5
There are four electrons, which is two pair.
