Atomic Structure and the Periodic Table

Every heartbeat, muscle contraction, and nerve impulse in the human body is fundamentally a transaction of invisible subatomic particles. When a nurse administers a saline intravenous drip, evaluates a patient’s blood potassium levels, or prepares a patient for a radioactive PET scan, they are directly manipulating and relying upon atomic structure. The physical properties of elements and the ways they interact to form life-sustaining molecules are not arbitrary; they are strictly governed by the architecture of atoms and their arrangement on the periodic table. To understand human physiology at a chemical level, one must first understand the blueprint of matter itself.
