## Orbit

1. Orbit is a well-defined circular path around the nucleus in which an electron revolves.

2. It represents the planar motion of an electron.

3. Orbit gives a definite path of an electron and this concept is not in accordance with the uncertainty principle.

4. All all orbits are circular.

5. Orbits do not have directional characteristics.

6. An orbit can accommodate electrons equal to 2n square where n represents the principal quantum number.

## Orbital

1. it represents the region in space around the nucleus in which the probability of finding the electron is maximum.

2. it represents the three-dimensional motion of an electron around the nucleus.

3. orbit does not specify a definite path and according to this concept, electrons may be anywhere in the region. This concept is in accordance with the uncertainty principle.

4. orbitals have different shapes, for example s-orbital is in spherical shape where p-orbital is in dumbbell shape.

5. Except s-orbitals all other orbitals have directional characteristics.

6. An orbital cannot accommodate more than two electrons.
