Chemistry · Structure of atom
हिन्दीGiven below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).\n Assertion (A): The energy of the orbitals in a hydrogen atom depends solely on the principal quantum number \( n \).\n Reason (R): In a hydrogen atom, the 2s and 2p orbitals have exactly the same energy. \nIn the light of the above statements, choose the correct answer from the options given below:
Correct answer · Option 1
Both (A) and (R) are true and (R) is the correct explanation of (A).
Explanation
In hydrogen atom, energy depends only on \( n \), which means orbitals with the same \( n \) (like 2s and 2p) are degenerate.
