a. The principal quantum number completely determines the energy of a given electron - True only for H.
b. The angular momentum quantum number, \( \ell \), determines the shapes of the atomic orbitals - True for all atoms.
c. The magnetic quantum number, \( m_{\ell} \), determines the direction that the atomic orbitals point in space - True for all atoms.
