Problem 27 Easy Difficulty

What are the possible values of the principal quantum number n? What does the principal quantum number determine?

Answer

The principle quantum number $(n)$ is an integer that determines the overall size and energy of
an orbital. Its possible values are $n=1,2,3, \ldots \ldots$ and so on. The orbitals with higher values of $n$
have greater energies than the orbitals with the lower values of $n$ . As the value of $n$ increases,
the energy of the orbital increases.

Video Transcript

principal quantum numbers we're in help determine be size, an amount of energy of an orbital. The principal quantum numbers must be whole numbers or intruders. So when can be won and could be, too, and could be three in central. As the principal quantum number increases, so does the size and the energy off the orbital's.
