It is an three dimensional space around the nucleus around which the probability of find the electron is maximum |
| It represent planar motion of electron around the nucleus |
It is the three dimensional motion around the nucleus |
| It have circular or disc like shape |
Different orbitals have different shapes such as s- orbital spherical shapes. |
