The maximum number of electrons in each energy level can be calculated using the formula 2n^2, where 'n' is the principal quantum number or energy level number. Thus, the first energy level can hold up to 2 electrons, the second up to 8, the third up to 18, and so on. This principle is fundamental in understanding the arrangement of electrons around an atom and plays a crucial role in the study of chemistry and physics.
