If you mean SiO2, which is a macromolecule- each silicon is bonded to 4 oxygen atoms and each oxygen to two silicon atoms. There are no non-bonding pairs of electrons on the on the silicon atom but ther are two on each oxygen atoms.
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.
An HCl molecule contains 3 nonbonding pairs..
3 non bonding pairs. Fluorine is in group 17 and has an outer shell configuration of 2s2, 2p5. Just one electron in the fluorine atom is unpaired the other 6 are paired

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.

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
The Non-bonding occur in the hypothalmus and enter the cortex.
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.
