What is the maximum number of electrons in the following energy level? n = 4

Thus, the fourth level can hold up to 32electrons: 2 in the s orbital, 6 in the three p orbitals, 10 in the five d orbitals, and 14 in the seven f orbitals. The sublevels of the first four principal energy levels and the maximum number of electrons that the sublevels can contain are summarized in Table 5.1.

hope this helps.

Because a model would make the investigation easier to understand
