There are two lone pairs of electrons on the oxygen atom in the Lewis structure of CH3OH.
There are two lone pairs of electrons in the most stable Lewis structure of the nitrate ion (NO3-). The nitrogen atom has a full octet (eight electrons) and does not have any lone pairs in this structure.
There are two lone pairs of electrons in the Lewis structure of a phosphate ion (PO4^3-). Each oxygen atom has two lone pairs of electrons, totaling 8 lone pairs for the four oxygen atoms in the phosphate ion.
There are two lone pairs of electrons in the Lewis structure of hydrazine (H2NNH2), one on each nitrogen atom. These lone pairs contribute to the molecule's overall geometry and reactivity.
There are 6 lone pairs as 3 lone pairs in either F atom.

In the Lewis structure of calcium sulfide (CaS), calcium donates its two valence electrons to sulfur, forming a bond. Calcium, being in group 2 of the periodic table, has no lone pairs of electrons in its final state after bonding. Therefore, in the Lewis structure of calcium sulfide, there are zero lone pairs of electrons associated with the calcium atom.
There are 6 lone pairs as 3 lone pairs in either F atom.
In the Lewis structure for methyl chloride (CH₃Cl), chlorine is bonded to carbon and has three lone pairs of electrons. Chlorine, being in Group 17 of the periodic table, has a total of seven valence electrons; it uses one of these to bond with carbon, leaving three lone pairs.
In the Lewis structure of a phosphate ion (PO₄³⁻), there are no lone pairs of electrons on the phosphorus atom, as it forms four bonds with oxygen atoms. However, each of the three oxygen atoms that carries a negative charge has two lone pairs of electrons. Thus, the total number of lone pairs in the phosphate ion is six (three oxygen atoms each contributing two lone pairs).
In the Lewis structure for a molecule of ammonium (NH₄⁺), nitrogen has no lone pairs of electrons. Instead, it forms four covalent bonds with four hydrogen atoms, using all of its valence electrons in bonding. This results in a positively charged ammonium ion, with nitrogen having a complete octet through these bonds.
NONE!!! Each bonding electron in carbon is paired with the bonding electron in each of the four hydrogens. So there are no lone pairs.
In a Lewis dot structure for an oxygen atom, there should be six dots. Lone pairs of electrons are represented by dots around the symbol for the atom. Oxygen has six valence electrons, so it will have a total of six dots in its Lewis dot structure.
H-:O:-H Two lone pair around the oxygen. ( not drawn to Lewis dot structure standards )
