A molecule is a group of two or more atoms held together by chemical bonds. These atoms can be of the same element, such as in an oxygen molecule (O2), or they can be of different elements, as in a water molecule (H2O). Molecules are the smallest particles of a chemical compound that retain the chemical properties of that compound.
The forces that hold atoms together in a molecule are called chemical bonds. The most common types
Molecules are fundamental to all matter. They are the building blocks of substances, from simple gases like
