Question

What is a quantum number explain each tybe with examples??

Answer 1

The quantum numbers------
First quantum number is the principle quantum number n

which can have any positive integer value....
n=1,2,3,...........

In the Bhor's atomic model.....
it represents the energy level of each electron.......

each orbital will have a value of n
nd'larger the value is,farther it will be from nucleus.......

Next quantum number is the angular momentum l


it can have value from 0 to n-1...

(l) describes the shape of orbitals.......

∆Magnetic quantum number
m sub l

m= -l.......l

it can have the value from negative l positive l

Last Quantum number....... spin quantum number....

m(s)= +1/2 or -1/2
every electron in an atom have a unique set of quantum numbers....

no 2 electrons in an atom can hv precisely same quantum quantum number sets.......
it is stated by the Pauli exclusion principle...
Hope it helps!!!
