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.
Water molecules (H 2 0) are very simple. They are made of two hydrogen (H) atoms bonded to one oxygen (O) atom. All water molecules are the same, but they are different from the molecules of any other substance. A water molecule is the smallest possible piece of water.You can break it up into smaller pieces, but they wouldnât be water anymore.hey can even be made up of just one atom. The element argon is a one-atom molecule. Other molecules can consist of two atoms of the same element. The oxygen molecule is made up of two oxygen atoms bonded together.
