Question 2 (Choice 1) - CBSE Class 12 Sample Paper for 2022 Boards [Term 2] - Physics - Solutions to CBSE Sample Paper - Physics Class 12

Last updated at April 16, 2024 by

Consider two different hydrogen atoms. The electron in each atom is in an excited state. Is it possible for the electrons to have different energies but same orbital angular momentum according to the Bohr model? Justify your answer. 

Answer

NO,

Because according to Bohr's model,

En = -13.6/n 2  and electrons having different energies belong to  different levels having different values of n.

So, their angular momenta will be different, as 

L = mvr = nh/2π
