Planck’s Quantum Theory -
Atom and molecules could emit (or absorb) energy only in discrete quantities known as quanta and not in a continuous manner.
-
Principal Quantum Number -
The principal quantum number determines the size and too large extent the energy of the orbital.
-
Principal Quantum Number (n) -
It is a positive integer with value of n = 1,2,3.......
-
Azimuthal Quantum Number(l): -
It defines the three-dimensional shape of the orbital.
-
