Which force binds atoms together to form molecules?

• A. Van der Waals forces
• B. Hydrogen bonds
• C. Ionic interactions
• D. Covalent bonds

Answer: (D)

Verified step by step guidance

1. Understand that molecules are formed when atoms share electrons to achieve stable electron configurations.
2. Recognize that covalent bonds involve the sharing of electron pairs between atoms, creating a strong connection that holds the atoms together in a molecule.
3. Differentiate covalent bonds from other forces: Van der Waals forces and hydrogen bonds are weaker intermolecular forces, while ionic interactions involve the transfer of electrons and formation of ions rather than sharing.
4. Recall that Van der Waals forces and hydrogen bonds typically occur between molecules, not within a molecule to hold atoms together.
5. Conclude that the force responsible for binding atoms together to form molecules is the covalent bond, due to the sharing of electrons between atoms.
