JEE Main Chemistry question
**Statement 1:** In a multi-electron atom, the energy of the orbital is independent of the azimuthal quantum number () for a given principal quantum number (). **Statement 2:** In a hydrogen atom, the energy of the electron depends completely on the principal quantum number ().
Answer: (D)
Solution
In a multi-electron atom, shielding and penetration effects make orbital energy depend on both and (following the rule, ns<np<nd<nf), so Statement 1 is false. In a one-electron hydrogen
