Question

derive an expression for bohr magneton​

Answer 1

Answer:

According to Bohr's model, the magnetic moment of an electron is μl = lπr2 = (evR)/2 here 'e' is an electron charge, 'v' is its speed in the orbit and 'r' is the corresponding radius of the orbit. But, mevr = l, the angular momentum, here the negative sign indicates that → and → are in opposite directions.
