The energies of orbitals in hydrogen -like spectries depend on the quantum number (s) …….

Assertion : In hydrogen and hydrogen like species, orbital energy depends only on the quantum number n whereas in multi-electron atoms it depends on quantum numbers n and l. Reason : The principle quantum number determines the size and the energy of the orbital.

For a one-electron atom, the set of allowed quantum number is -

(A) 3s, 3p and 3d subshells in hydrogen have same energy. (R) Energy of subshells in hydrogen atom, depends on the principle quantum number (n) and azimuthal quantum number (l).

The force acting on the electron in a hydrogen atom depends on the principal quantum number as
