Which of the following is not a characteristic of a covalent bond?
It is formed by sharing of electrons.
It results in the formation of molecules.
It is generally weaker than ionic bonds.
It involves the transfer of electrons from one atom to another.
A covalent bond is formed by the sharing of electrons between atoms. The shared electrons are attracted to both the nuclei, thus resulting in the formation of a stable molecule. Covalent bonds are generally weaker than ionic bonds, and they can be polar or nonpolar depending on the electronegativity difference between the atoms involved) In contrast, ionic bonds involve the transfer of electrons from one atom to another, resulting in the formation of ions rather than molecules.
