Verified step by step guidance1
Understand the types of chemical bonds: Ionic bonds involve the transfer of electrons from one atom to another, resulting in charged ions. Covalent bonds involve the sharing of electron pairs between atoms.
Identify the key characteristic of covalent bonds: In covalent bonding, atoms share pairs of electrons to achieve a full outer shell, which stabilizes the atoms involved.
Differentiate between covalent and other types of bonds: Unlike ionic bonds, which involve electron transfer, covalent bonds involve electron sharing. Hydrogen bonds are weak interactions between a hydrogen atom and an electronegative atom, while polar covalent bonds involve unequal sharing of electrons.
Consider the context of the problem: The question specifically asks about the sharing of a pair of electrons, which is a defining feature of covalent bonds.
Conclude that the correct answer is 'Covalent' based on the understanding that covalent bonds are formed by the sharing of electron pairs between atoms.
