There are zero pair
There are two lone pairs of electrons on the As atom in AsCl3.
There are two lone pairs on the arsenic atom in ASO2.
There is 1 lone pair on the phosphorus atom in PH3.
Water (H2O) has two lone pairs on the oxygen atom.
In an oxygen molecule (O2), each oxygen atom has 3 lone pairs of electrons.
There are two lone pairs of electrons on the As atom in AsCl3.
No lone pairs
The lone pairs are on the bromine atom- 3 in all.
There are two lone pairs on the arsenic atom in ASO2.
There are three lone pairs present in chlorine atom
Boron trichloride is an inorganic compound that is a valuable reagent in organic synthesis. It has zero lone pairs on the central atom.
There is 1 lone pair on the phosphorus atom in PH3.
In the sulfate ion (SO₄²⁻), there are no lone pairs on the sulfur atom, but there are two lone pairs on each of the four oxygen atoms. Therefore, the total number of lone pairs in the sulfate ion is 8 (2 lone pairs per oxygen atom × 4 oxygen atoms).

Water (H2O) has two lone pairs on the oxygen atom.
The Si has no lone pairs, but each F has 6 lone pairs. Thus 6 x 4 = 24 lone pairs, total.
In the molecule OBr2 (dibromine monoxide), the oxygen atom has two lone pairs of electrons. The oxygen is bonded to two bromine atoms, which accounts for the two bonding pairs. Therefore, OBr2 has a total of two lone pairs on the oxygen atom.
