Answer: (D)

Verified step by step guidance

1. Understand the types of chemical bonds: Chemical bonds are the forces that hold atoms together in compounds. The main types are ionic, covalent, metallic, and hydrogen bonds.
2. Define a covalent bond: A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons. This sharing allows each atom to attain the electron configuration of a noble gas, achieving stability.
3. Differentiate between bond types: In an ionic bond, electrons are transferred from one atom to another, creating ions that attract each other. In a metallic bond, electrons are shared among a lattice of atoms, allowing them to move freely. Hydrogen bonds are weak attractions between a hydrogen atom and an electronegative atom.
4. Identify the bond type where electrons are shared: Among the bond types listed, covalent bonds are characterized by the sharing of electrons between atoms.
5. Conclude with the correct answer: Based on the definition and characteristics of covalent bonds, the type of bond where atoms share electrons is a covalent bond.
