Explanation:

Identify subatomic particles in the nucleus

The nucleus of an atom contains protons and neutrons. Protons carry a positive charge, while neutrons carry no charge. Together, they make up almost all of the atom's mass.

Determine the mass of a proton

The mass of subatomic particles is measured in atomic mass units (amu). A single proton has a mass of approximately \(1\text{ amu}\).

Locate chemical energy storage

Chemical energy is potential energy stored within the chemical bonds holding atoms together in molecules. When these bonds are broken or formed during chemical reactions, energy is released or absorbed.

Identify major elements in the human body

Four elements make up about 96% of the human body's mass. These essential elements are Oxygen (\(\text{O}\)), Carbon (\(\text{C}\)), Hydrogen (\(\text{H}\)), and Nitrogen (\(\text{N}\)).
