For each level (main quantum number) number "n", there are 2 times n squared electrons. The reasons are related to the Pauli Exclusion Principle, meaning that no two electrons can have the same values for all four quantum numbers.

The element with four electrons in energy level n=4 is zirconium (Zr), which has the atomic number 40. In its electron configuration, zirconium has two electrons in the 4s subshell and two in the 4p subshell, totaling four electrons in the n=4 energy level.
Unit four is typically identified by the color green. This color coding helps in distinguishing it from other units for easy reference and organization.
The element that has four electrons in energy level n=3 is arsenic (As), which has the atomic number 33. In its electron configuration, arsenic has the distribution of electrons as follows: 1s² 2s² 2p⁶ 3s² 3p³, where the 3s and 3p orbitals together account for the four electrons in the n=3 energy level.
