The energy of an electron in the hydrogen atom is determined by A)the principal quantum number ( n)only. B)the angular momentum quantum number ( l)only. C)the principal and angular momentum quantum numbers ( n & l ). D)the principal and magnetic quantum numbers ( n & m_l)_. E)the principal, angular momentum and magnetic quantum numbers.

Question

The energy of an electron in a hydrogen atom is determined solely by the principal quantum number (n). This is because, in hydrogen, energy levels are degenerate for different values of the angular momentum (l) and magnetic (m) quantum numbers, meaning these do not affect the energy.
