Final answer:
The chemicals that make up the body are divided into two major categories: organic and inorganic.
Step-by-step explanation:
The chemicals that make up the body are divided into two major categories: organic and inorganic.
Organic compounds are molecules built around the element carbon and are the main chemical components of living organisms. They are made up of large molecules called macromolecules, which are formed by smaller molecules bonding together.
Inorganic compounds can be classified into ionic compounds and molecular compounds. Ionic compounds consist of a three-dimensional array of alternating positive and negative ions and are represented by empirical formulas, while molecular compounds have individual molecules with specific formulas.
