Hydrogen atom model - Study guides, Class notes & Summaries

What is the difference between a compound and a molecule? - Answer-Chemical bond = molecule crystalline structure or atom by itself -- not a molecule 1 A molecule consists of two more atoms, which can be the same or different types of atom, that are linked by a chemical bond. A molecule of H2 or O2 is still a molecule, but not a compound. 2. A compound is usually a molecule as well. To be a compound, it has to have two different types of atoms, such as H2O. 3. Some compounds like NaCl are ...
