A compound involves two or more different elements bonded together. Molecules can also be formed from a single element, for example, the nitrogen molecule which consists of two nitrogen atoms bonded together; since only one element is involved, that does not qualify as a compound.
Elements and compounds are pure substances. Elements are composed of only one kind of atom and compounds are composed of two or more elements that are chemically combined. Mixtures are not pure substances, as they are composed of two or more components that are not chemically combined.

A molecule is the smallest unit of most chemical compounds. Scientists use a kind of shorthand called a chemical formula that shows the type and number of elements in a molecule. For example, a water molecule is written as H2O, which means there are 2 atoms of Hydrogen and 1 atom of Oxygen.
Derivatives of CARBON are termed as organic compounds or organic molecules
They are chemical compounds
Elements and compounds are pure substances. Elements are composed of only one kind of atom and compounds are composed of two or more elements that are chemically combined. Mixtures are not pure substances, as they are composed of two or more components that are not chemically combined.
Compounds are composed of elements. Elements are composed of sub-atomic particles (electrons, protons, and neutrons).

Oxygen is composed of oxygen atoms.
"A chemical compound is a pure chemical substance consisting of two or more different chemical elements"So says wikipedia!O2 does not have two or more different chemical elements and so cannot be a compound. It is, however, a molecule (which only requires 2 or more atoms connected by bonds).To clarify - all compounds are molecules...but not all molecules are compounds.O2 represents a molecule of oxygen.An atom is the smallest component of any element having all the chemical properties of that specific element.A molecule is the simplest complete structural unit of an element or compound that can exist in nature.A compound is a substance consisting of two or more different elements or molecules formed by the chemical union of two or more elements or molecules in definite proportion by weight.

chemical bonds
A compound is a pure chemical substance that consists of two or more different chemical elements. It contains a fixed ratio of atomsthat are held together in a defined spatial arrangement by chemical bonds.
