Which of the following is formed when two atoms combine through a chemical interaction?

• A. An ionic lattice
• B. A proton
• C. A chemical bond
• D. A molecule of water

Answer: (C)

Verified step by step guidance

1. Understand that when two atoms combine through a chemical interaction, they form a connection called a chemical bond.
2. Recognize that a chemical bond is the force holding atoms together in a compound, which can be ionic, covalent, or metallic in nature.
3. Note that an ionic lattice is a large, repeating structure formed by many ions, not just two atoms combining.
4. Recall that a proton is a subatomic particle inside an atom's nucleus, not a product of atoms combining.
5. Identify that a molecule of water is a specific example of atoms bonded together, but the general term for the connection formed is a chemical bond.
