This document discusses the structure and composition of matter. It explains that all matter is made up of elements, which are composed of atoms. Atoms contain protons, neutrons, and electrons. Elements can bond together through ionic bonds, covalent bonds, or hydrogen bonds to form molecules or compounds. Some important compounds are electrolytes, acids, bases, and salts. Chemical reactions cause bonds to form or break as atoms rearrange. The human body relies on many chemical processes and requires maintaining a narrow pH range in the blood for survival.
