Water is formed when oxygen and hydrogen atoms combine, and it takes a total of three atoms to make a water molecule. Two of the atoms are hydrogen and the last atom is oxygen, hence the chemical formula H2O. More »

Elements are made of atoms, which are particles that represent the most basic form of an element. An atom is the smallest particle of an element and cannot be further divided without becoming a less complex particle; in ... More »

A compound is made up of two or more atoms that are bonded together chemically. Compounds can be separated into smaller components through chemical reactions. Water is an example of a compound because it is made from ato... More »

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 throu... More »

The most abundant elements in ocean water are hydrogen and oxygen, the two elements that constitute the water molecule. Excluding the water molecule, the most abundant elements in ocean water are sodium and chlorine. More »

The covalent bonds between hydrogen and oxygen in a molecule of water are the most polar. Water is a covalent molecule, meaning the two atoms of hydrogen and the one atom of oxygen share electrons. More »

The two elements that make up a molecule of water are hydrogen and oxygen; there are two hydrogen atoms and one oxygen atom, resulting in the chemical formula H2O. Hydrogen and oxygen bond together due to the number of e... More »
