Organic molecules are made up of atoms that are bonded together. Inorganic molecules are made up of atoms that are not bonded to each other. Organic molecules contain carbon atoms, hydrogen atoms, nitrogen atoms, oxygen atoms, and phosphorus atoms. Organic molecules also contain a few sulfur atoms.

There are more than 100 types of organic molecules. Hydrocarbon fuels are some examples of organic molecules. They are composed of carbon and hydrogen atoms. They are used to create energy. Nucleic acids are organic molecules crack rocks that make up the genetic code. These molecules are very important for the growth and development of living cells. Enzymes are organic molecules that speed up chemical reactions.

Inorganic molecules include carbon atoms, hydrogen atoms, oxygen atoms, and phosphorus atoms. They include a variety of elements such as sodium, potassium, magnesium, and iron.

Molecules are one of the most common forms of matter found on Earth. They make up the food we eat and the air we breathe.

Fats, nucleic acids, carbohydrates, enzymes, proteins, and hydrocarbon fuels are examples of organic molecules.

Non-metals, salts, metals, acids, bases, and things derived from a single element are examples of inorganic compounds.
