explain the difference between a compound and a molecule. use information in the reading prompt to support your answer.

Explanation:

A molecule is made up of two or more atoms bonded together. These atoms can be of the same element (e.g., \(O_2\), \(N_2\)) or different elements. A compound is a type of molecule that consists of two or more different elements chemically bonded together. So, all compounds are molecules, but not all molecules are compounds. For example, \(O_2\) (a molecule of oxygen) is not a compound because it only has one type of element (\(O\)), while \(H_2O\) (water) is a compound as it has two different elements (\(H\) and \(O\)) chemically bonded.

Answer:

A molecule is two or more atoms bonded (same or different elements). A compound is a molecule with two or more different elements. All compounds are molecules, but not vice - versa (e.g., \(O_2\) is a molecule but not a compound; \(H_2O\) is both a molecule and a compound).
