Modern atomic theories explain the structure and behavior of the atom much better then the other atomic theory. Modern atomic theory takes into consideration the probability of finding the electron in space. The orbital is therefore a space a region around the nucleus where probability of finding electron is maximum. Orbital is the most parable space in which electron spends most of its time. When electron remains in the same orbital its energy remain the same and does not changes.

Orbit	Orbital
It is well-defined fixed path of an electron around the nucleus of an atom. The shape of an orbit in fixed. Maximum number of electrons that can be placed in an orbit is given by , where ”n” is number of orbit. It is against the Heisenberg principle.	i. It is a region around nucleus where probability of finding electron is maximum ii. As electron have wave like properties therefore orbital have different shapes. iii. An orbital can have maximum to two electrons. iv. It is according to the Hisenberg Principle.
