Question

Quizplus · Accepted Answer

In an isolated atom, the energy of an electron primarily depends on the principal quantum number (n) only, according to the Bohr model of the atom and quantum mechanics. The other quantum numbers (l, $m_l$, and $m_s$) determine the shape, orientation, and spin of the electron's orbit, but not the energy in a simple, isolated atom without external fields.
