Some elements exist as monoatomic elements such as Ne, Pb, Al, and C.
Some elements exist as polyatomic molecules such as P4, S8, N2, and O2,
A molecule is two or more atoms that are bonded together. For instance, oxygen is rarely found as just an O atom, but instead is found as two atoms bonded together in one molecule, O2. Both O and O2 are elements because they are composed of only one type of element. A compound is composed of two different types of elements. Can you have an atom of a compound like you can an element, or can you only have a molecule of a compound?
