Practice portal › Atoms › Bohr Model of the Hydrogen Atom

The angular momentum for the electron in Bohr's orbit is L. If the electron is assumed to revolve in second orbit of hydrogen atom, then the change in angular momentum will be

Asked in JEE Main 10th April 1st Shift 2023 · Postulates, radius, speed and angular momentum

• (1) zero
• (2) 2L
• (3) L
• (4) /L2

Step-by-step solution

Why the other options are wrong

• (1) Thinks L is the same in all orbits.
• (2) Gives the new value, not the change.
• (4) Takes L∝1/n.
