Oxygen has two non-bonding pairs of electrons.
Serine does not have any non-bonding electrons pairs. Please click on the related link to see a structural formula for serine.
In BF3, there are 3 bonding electron pairs and 0 non-bonding electron pairs. Boron has 3 valence electrons, and each fluorine contributes one electron for bonding, giving a total of 3 bonding pairs in the molecule.
In HCl, there are no non-bonding pairs of electrons. The molecule consists of one hydrogen atom covalently bonded to a chlorine atom.
A fluorine atom has three non-bonding pairs of electrons. This is because fluorine has seven valence electrons, with one being used in the covalent bond and the remaining six being non-bonding pairs.

Each iodine atom in a molecule of carbon tetraiodide has three non-bonding pairs of electrons.
The Lewis structure of PF3 shows that the central phosphorus atom has one non-bonding electron pair and three bonding electron pairs. Phosphorus has five valence electrons, and in PF3, one is non-bonding while the other three are shared in bonds with the fluorine atoms.
In HCl, there are no non-bonding pairs of electrons. The molecule consists of one hydrogen atom covalently bonded to a chlorine atom.
A fluorine atom has three non-bonding pairs of electrons. This is because fluorine has seven valence electrons, with one being used in the covalent bond and the remaining six being non-bonding pairs.
There are two non-bonding pairs of electrons in Cl4. Each chlorine atom in Cl4 has 7 valence electrons, forming single covalent bonds with the other chlorine atoms, leaving two lone pairs on each chlorine atom.
Consider: Number of bonding domains on the central atom Number of non-bonding electron pairs (lone pairs) on the central atom
Consider: Number of bonding domains on the central atom Number of non-bonding electron pairs (lone pairs) on the central atom
Urea has a total of 10 non-bonding valence electrons. There are 4 non-bonding electron pairs on the oxygen atoms and 2 on the nitrogen atom in the structure of urea.
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.
