No. When atoms share electron pairs they form covalent bonds.
Isotopes are atoms having different numbers of neutrons.
Covalent bonds
Covalent bonds. (Atom bindings that share electron pairs)
Covalent bond, in chemistry, the interatomic linkage that results from the sharing of an electron pair between two atoms. The binding arises from the electrostatic attraction of their nuclei for the same electrons.
A covalent bond is a chemical bond between atoms that share electrons. It is the stable balance of the attractive and repulsive forces and the result of sharing of electron pairs between the atoms.
a carbon atom can share electrons with up to four other atoms.
molecules
Electrostatic attraction for electron pairs hold atoms together. When atoms bond into a molecule, they share electrons, each contributing one electron to a pair. Since the nuclei of the atoms are positive and the electrons are negative, both nuclei are attracted to the shared pair, and stay near each other.
The bond that occurs when atoms share electrons is Ionic Bond
yeap!
covalent bonds
The atoms share two pairs of electrons.
