Two individual hydrogen atoms can be bonded together by a covalent bond. Since each hydrogen atom contains one electron, they can evenly share their electrons and form a strong covalent bond. More »

A sample of a given element can consist of a single atom of that element, and so there is no fixed quantity of molecules required to make up an element. In the universe at large, however, hydrogen is by far the most abun... More »

A molecule composed of two hydrogen atoms and one oxygen atom is a molecule of water. The structure of water is written as H20, which signifies that two hydrogen (H) atoms and one oxygen (O) atom make up the molecule. More »

A polar covalent bond is a type of bond between two or more atoms in which the atoms do not share their pair of electrons equally. In this type of bond, one of the atoms is stronger than the other and attracts the electr... More »

Sucrose is a polar molecule because the bond between the oxygen and the hydrogen atoms gives the oxygen a slight negative charge and the hydrogen a slight positive charge. The negative and positive areas attract the pola... More »

A nonpolar covalent bond is a type of bond between two identical nonmetallic atoms where the two electrons are shared equally by each atom. It is different from a polar covalent bond, in that involves the electrons being... More »

Dihydrogen monoxide, sometimes referred to as dihydrogen oxide, is a colorless, odorless compound of two hydrogen atoms locked via a covalent bond with a single atom of oxygen. The resulting molecule is sometimes abbrevi... More »
