A compound is a molecule that contains at least 2 different elements. A molecule is formed when 2 atoms chemically form.
A compound is a pure substance that contains two or more elements chemically combined. E.g, sodium chloride, carbon dioxide. A molecule is a group of at least 2 or more atoms chemically combined by covalent bonds. E.g, oxygen (O2), chlorine gas (Cl2)
1. A molecule is a group of at least two atoms chemically combined in definiteproportions.For example, a water molecule (H2O) is always composed of two atoms of hydrogen chemically combined with one of oxygen. (a 2 hydrogen :1 oxygen proportion)If you have a combination of three hydrogen atoms with one oxygen atom(3 hydrogen:1 oxygen ) , the combination is notwater;this is what is meant by defininte proportions.2. Molecules are held together by covalent bonds;i.e., the sharing of pairs of electrons holds the atoms together. Also, molecules are held together by columbic forces or forces of electrostatic attraction in case of ionic compounds.Additional Note : * If different kinds of atoms combine to form a molecule, thesubstance formed is called a compound.An example of a compound is water.* If atoms of the same kind combine to form a molecule, the substance iscalled an element.Example , oxygen (O2)

That's called.. a molecule.
Most often, at least one chemical compound.
When they combine chemically, they form compounds, which can have very different chemical properties than the constituent elements.If they are combined physically, they only form mixtures, alloys, or colloids.
A molecule is formed when two or more atoms join together chemically. A compound is a molecule that contains at least two different elements. All compounds are molecules but not all molecules are compounds.
When two identical atoms react, a chemical bond is formed. Sometimes the bond can be polar, non polar, or ionic.
