(Question)
Answer the following question given this paragraph:   Consider the example of water forming from hydrogen and oxygen. Both hydrogen and oxygen gases exist as diatomic (“two-atom”) molecules. These molecules are the reactants in the reaction. The Figure below shows that bonds must break to separate the atoms in the hydrogen and oxygen molecules. Then new bonds must form between hydrogen and oxygen atoms to form water molecules. The water molecules are the products of the reaction.   Q: What is the name for a molecule with two atoms?   Choices:  - hydrostatic  - ionized  - covalent  - diatomic  A:
(Answer)
diatomic
