A force that holds atoms together in a compound is a

• A. Ion
• B. Chemical formula
• C. Mass number
• D. Chemical bond

Answer: (D)

The main concept here is what holds atoms together in a compound. A chemical bond is the force that links atoms, allowing them to share or transfer electrons so they become more stable together. An ion is just a charged particle, not the binding force between atoms. A chemical formula describes which elements are present and in what ratios, but it doesn’t explain the force that holds the atoms together. The mass number is the total count of protons and neutrons in a nucleus, which is about the nucleus itself, not the bonds between atoms. For example, in water, hydrogen and oxygen atoms are held together by covalent bonds, illustrating how a chemical bond creates the connection that forms compounds. So the best answer is the chemical bond.
