Diatomic oxygen is a molecule.
Element: It is made up of similar atoms which are not bonded.The atoms in an element will have the same number of protons .
Molecule: it is a group of two or more atoms that are bonded chemically.
Compound: It is formed by two or more varied elements bonded to each other chemically.The elements combine in a fixed ratio.
Substance: It is matter which has fixed chemical composition.
Because oxygen can't be broken down any further, it's classified as an element. Elements are solitary atoms made up of pure substances.
Oxygen is the most prevalent element on Earth, and it is the third most plentiful element in the universe after hydrogen and helium. Two atoms of the element bond together at normal temperature and pressure to create dioxygen, a colorless and odorless diatomic gas with the formula O2.
Element : It is formed up of atoms that are similar but not bonded. An element's atoms will all have the same amount of protons.
Molecule: A molecule is a chemically bound collection of two or more atoms.
Compound: A compound is made up of two or more different elements that are chemically linked together. The components are arranged in a certain order.
Substance: Matter with a predetermined chemical makeup.
