This is a 3D water molecule that I made. H2O is the scientific name for water. It is called H2O because it has two hydrogen (H) (or white in model) atoms and one oxygen atom (O)(or red atom in model). In one drop of water, there are millions of these molecules. The form that water takes depends on the movement of the molecules of water. One of the most significant substances on earth is water. To live, both plants and animals must have water. There would be no life on earth if there was no water. People have many other uses for water, aside from drinking it to live.Water molecules are polar, with partial hydrogen positive charges, partial oxygen negative charges, and a twisted overall structure. This is because oxygen is more electronegative, which means that it is better at gathering electrons than hydrogen. Water is also an exceptional solvent.
