Compound.
When elements are combined in a substance, the product is called a compound. For example, a water molecule is a compound molecule containing the elements hydrogen and oxygen.
molecule. It is a shorthand way to represent the elements and their proportions in a compound. The formula provides information about the composition of the substance.
The four elements of empedocles is fire, water, earth and air

Water is a coumpound made up of two elements, hydrogen and oxygen, which makes the most basic unit of water a molecule, not an atom, which is the most basic form of an elements, so no elements contain water.
When two or more elements bond together they form a compound.
When two or more elements bond together they form a compound.
The scientist who proposed the law of definite proportions was Joseph Proust. He stated that elements always combine in specific and fixed proportions by mass to form compounds.
A molecule. elements are a series of atoms that form an element and several elements form a molecule.
A binary molecular compound is a molecule composed of two different elements. These elements share electrons to form covalent bonds, resulting in a stable structure. Examples include water (H2O) and carbon dioxide (CO2).
A carbon atom and four hydrogen atoms can combine together to form a methane molecule.
