Orbit
|
|
Orbital
|
|
i.
|
An orbit is a well-defined circular path around the nucleus in which the electrons revolve.
|
i.
|
An orbital is the three-dimensional space around the nucleus within which the probability of finding an electron is maximum (upto 90%)
|
|
ii.
|
It represents the planar motion of an electron around the nucleus.
|
ii.
|
It represents the three dimensional motion of an electron around the nucleus.
|
|
iii.
|
All orbits are circular and disc like.
|
iii.
|
Different orbitals have different shapes, i.e. s-irbitals are spherically symmetrical, p-orbitals are dumb-bell shaped and so on.
