Answer:
Step-by-step explanation:
The element that contains 5 electrons in the 4s and 4p sublevels is phosphorus (P), with the electron configuration:
1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹ 4p³
In this electron configuration, there are 2 electrons in the 4s sublevel and 3 electrons in the 4p sublevel, for a total of 5 electrons in those two sublevels.
