A subatomic particle is related to the atomic mass unit (amu) because the amu is a unit of measurement used to express the mass of subatomic particles such as protons, neutrons, and electrons. It is defined as one-twelfth the mass of a carbon-12 atom.

An electron is related to energy levels in an atom because energy levels represent the possible locations or orbits where electrons can be found. Electrons occupy different energy levels depending on their distance from the nucleus, with higher energy levels corresponding to greater distances.
