Question

angular momentum is quantized what do you mean by quantised here?explain in an understanding manner.​

Answer 1

Answer:

Bohr said that e- revolve around nucleus in fixed circular path called orbits, now he gave one postulate to this,that only those orbits are permitted in which  "Angular Momentum"(l=mvr)  is whole number multiple of h/2pi.

Explanation:

This means mvr=nh/2pi where n=1,2,3...

So we say that Angular Momentum is quantised, i.e the electrons will always be found in orbits and can't be found in between these orbits.

For your convenience i should tell you in general word quantized means "Form into quanta, in particular restrict the number of possible values of (a quantity) or states of (a system) so that certain variables can assume only certain discrete magnitudes."
