Those are different isotopes of the same element. Different isotopes of the same element have the same number of protons, but a different number of neutrons. There are a little over 100 known elements, but over 3000 different known isotopes.
molecule
Two atoms sharing three pairs of electrons have a triple bond.
a carbon atom can share electrons with up to four other atoms.
molecules
the shared valence electron pairs repel each other.
covalent bond
No. When atoms share electron pairs they form covalent bonds. Isotopes are atoms having different numbers of neutrons.
a carbon atom can share electrons with up to four other atoms.
Two atoms sharing three pairs of electrons have a triple bond.
molecules
The atoms share two pairs of electrons.
the shared valence electron pairs repel each other.
covalent bond
Helium and iodine, carbon and fluorine, and hydrogen and oxygen are three pairs of ions.
No. There is no such thing as a diatomic atom. A diatomic molecule is a molecule that contains two atoms. The number of lone pairs depends on what atoms are bonded.
By sharing electrons of two atoms to achieve pairs of bonding el's that are holding them together
Forces between electron pairs push the atoms apart.
