In I2 (iodine molecule), there is one bonding pair of electrons. Each iodine atom contributes one electron to the bond, forming a single covalent bond between the two iodine atoms. This results in a diatomic molecule held together by that single bonding pair.
Each iodine atom in a molecule of carbon tetraiodide has three non-bonding pairs of electrons.
In carbon monoxide (CO), there are no unshared pairs of electrons. All the electrons are involved in bonding between carbon and oxygen.
In GeCl4 (germanium tetrachloride), there are four bonding pairs of electrons. Each chlorine atom forms a single covalent bond with germanium to satisfy its octet.
Three bonding pairs, thus a pyramid.
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.
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.
Oxygen has two non-bonding pairs of electrons.
Methyl fluoride (CH3F) has three bonding pairs of electrons between carbon and hydrogen atoms in the methyl group, and one bonding pair of electrons between carbon and fluorine atoms. Therefore, there are a total of four bonding pairs of electrons in methyl fluoride.
There are four electrons, which is two pair.

Each iodine atom in a molecule of carbon tetraiodide has three non-bonding pairs of electrons.
An HCl molecule contains 3 nonbonding pairs..
In carbon monoxide (CO), there are no unshared pairs of electrons. All the electrons are involved in bonding between carbon and oxygen.
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.
Serine does not have any non-bonding electrons pairs. Please click on the related link to see a structural formula for serine.
In the Lewis structure of ethylene glycol, a total of 16 valence electrons need to be shown. There are 6 pairs of electrons that are bonding (forming bonds between O-H, C-O and C-C) and 2 pairs of electrons that are nonbonding (on the oxygen atoms).
In GeCl4 (germanium tetrachloride), there are four bonding pairs of electrons. Each chlorine atom forms a single covalent bond with germanium to satisfy its octet.
