How many electrons does the fourth energy shell have and why?

Asked by Sayoni Maiti | 28th Dec, 2013, 07:33: PM

Expert Answer:

The maximum number of electrons which can occupy a specific energy level is found by the following formula:

Electron Capacity = 2n2

The variable n represents the Principal Quantum Number or the number of the energy level in question.

For the fourth energy level:

n = 4

Hence the maximum electrons in the fourth energy level are = 2 x 42 = 32 electrons
