Answer:
Refer to the explanation.
Step-by-step explanation:
The image you've provided contains a table that is meant to be completed with information regarding the principal quantum number, the number of sublevels, and the types of orbitals in an atom.
The principal quantum number, often symbolized as 'n', basically determines the size and energy level of the orbitals. With each increase in the principal quantum number, the number of sublevels also increases.
I have attached an image with the principal quantum number's extended to 7.
