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.
Â· just now. Report Abuse. Water is a mixture because it is made up of molecules that are composed of two atoms of hydrogen and one atom of oxygen. An atom is the smallest particle of a pure substance (element) that has all the properties of that substance.A molecule is made up of a number of atoms bonded together.ater is not an element but it is an organic chemical that is required for life as we know it to exist. H2O is pure water. Water can have a lot of other things in it to make it not a pure substance. Water is the standard of our scientific realm. It is the universal solvent (water dissolved the Grand Canyon, ya know).
