A single molecule of water consists of three atoms. H2O is built from a single atom of oxygen that is single-bonded with two atoms of hydrogen.
Oxygen is generally eager to bind with hydrogen. These atoms bond strongly with each other, and the resulting water molecule is unusually stable and resistant to decomposition. Within each water molecule, oxygen is bound to hydrogen by a covalent bond consisting of two shared electrons per hydrogen atom. Oxygen's other, unshared, electrons tend to push against the hydrogen atoms and force them toward one side of the oxygen, resulting in an asymmetrical electromagnetic polarity that permits weaker hydrogen bonds between molecules.Learn More
Hydrogen bonds hold together the atoms in a water molecule. A single water molecule is made up of two hydrogen atoms and one oxygen atom.Full Answer >
A polar molecule is a particle consisting of two or more covalently bonded atoms with an asymmetric distribution of charges. This occurs in molecules that are asymmetric along at least one axis when one side contains atoms with a greater electronegativity than the other side. This results in shared electrons spending more time on the side with greater electronegativity, causing that side to have a greater negative charge most of the time.Full Answer >
Water contains two types of elements, hydrogen and oxygen, and three atoms in total. Because hydrogen is the most abundant element in the universe and oxygen is also common, water is thought to be a common chemical throughout the universe.Full Answer >
A molecule is a group of two or more atoms bonded together, while a compound is a group of two or more atoms bonded together where the atoms are from at least two types of elements. All compounds are also molecules, but all molecules are not compounds.Full Answer >
