∙ 13y agoNo, there are no lone pairs in a molecule of CH3. All atoms in CH3 are involved in bonding, so there are no unshared pairs of electrons on the carbon or hydrogen atoms.
Two atoms sharing three pairs of electrons have a triple bond.
molecules
Helium and iodine, carbon and fluorine, and hydrogen and oxygen are three pairs of ions.
the shared valence electron pairs repel each other.

No. When atoms share electron pairs they form covalent bonds. Isotopes are atoms having different numbers of neutrons.
The pairs of valence electrons that do not participate in bonding in a diatomic oxygen molecule are called lone pairs. These pairs of electrons are not involved in forming the double bond between the oxygen atoms in O2.

molecules
Helium and iodine, carbon and fluorine, and hydrogen and oxygen are three pairs of ions.
When two pairs of electrons are shared between two atoms, a double bond is formed. In a double bond, two electron pairs are shared between the atoms, resulting in a stronger bond compared to a single bond.
the shared valence electron pairs repel each other.
The atoms share two pairs of electrons.
There are four electrons, which is two pair.
That would depend on the given system of linear equations which have not been given in the question
By sharing electrons of two atoms to achieve pairs of bonding el's that are holding them together
