Fox was uncharacteristically quiet as he drove, and if it werenât for his occasional turning of the steering wheel, I would have thought someone had crafted a wax-statue of him and stuck it next to me. âThanks for driving me,â I finally said, just to say something.
Everything is made of atoms. An atom is the smallest particle of an element, like oxygen or hydrogen. Atoms join together to form molecules. A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom. That's why water is sometimes referred to as H2O. A single drop of water contains billions of water molecules.
Chemistry. Water MoleculeThis 3D image shows one oxygen atom (red) and two hydrogen atoms, forming a water molecule.{Public Domain image}. ^Back to Main Information PageWater is, in fact, a chemical. Its chemical formula is H2O (or, less commonly, HOH), which is what this website is named after.ach water molecule is made of two hydrogen atoms and one oxygen atom, thus there are two H atoms and one O. The atoms are joined by covalent bonding, meaning that they share electrons (as opposed to ionic bonding, in which atoms completely transfer electrons).
