The difference between an elemental molecule and a compound molecule is the type of atoms with which it is made.

Yes, that's correct! The distinction between elemental molecules and compound molecules lies in the types of atoms they contain: 1. **Elemental Molecules**: These are made up of only one type of atom. For example, oxygen (O₂) is an elemental molecule consisting of two oxygen atoms. Other examples include nitrogen (N₂) and hydrogen (H₂). Elemental molecules represent the simplest form of matter that retains the properties of the element. 2. **Compound Molecules**: These are made up of two or more different types of atoms that are chemically bonded together. For example, water (H₂O) is a compound molecule consisting of two hydrogen atoms and one oxygen atom. Other examples include carbon dioxide (CO₂) and sodium chloride (NaCl). Compound molecules have properties that are distinct from the individual elements that compose them. In summary, elemental molecules consist of a single type of atom, while compound molecules consist of multiple types of atoms.
