The allowed values of n for the Li²⁺ ion are A) 1 to ∞ B) 2 to ∞ C) 3 to ∞ D) any real number E) 1 to 10

Question

Quizplus · Accepted Answer

The allowed values of $n$ for any ion or atom in quantum mechanics, which determines the principal quantum number and thus the energy levels an electron can occupy, start from 1 and theoretically extend to infinity. This is because $n$ represents the shell level in an atom, starting from the closest to the nucleus at $n=1$ and moving outward.
