The definition of a molecule is two or more atoms which have chemically combined to form a single species. Therefore when the two hydrogen atoms combine with the one oxygen atom, you get a single substance.
Gold is an element made up of atoms. Each gold atom is a single, indivisible unit. It is not a molecule because it does not consist of multiple atoms chemically bonded together.
C8H9NO2 is a compound because it is made up of two or more different elements chemically bonded together. It is not a molecule by itself, but it can form molecules when its atoms are bonded in a specific arrangement.
Water is a molecule composed of two hydrogen atoms and one oxygen atom bonded together. It is not a mixture, which is a combination of different substances that are not chemically bonded, nor a compound, which is a substance made up of two or more different elements chemically bonded together.
Atoms of two or more elements chemically bonded.
A group of atoms chemically joined together is called a molecule. Molecules can be made up of two or more atoms of the same or different elements bonded together.
Molecule and compound are two words that mean a substance made of atoms that are bonded together.
A molecule because there are 2 oxygen atoms bonded.
