What is the actual concept of an electron?

Question

On what basis does electrons revolve around the nucleus in different orbits?What decides the shape of an orbital?

Answer 1

An electron has negative charge, so it is bound to the positively charged nucleus by electromagnetic forces. Not all electrons revolve. Some have angular momentum. Some (s-orbitals) don't. The shape of the orbital is determined by solving the Schrodinger equation for the electron bound to the nucleus by a Coulomb potential. Only certain sizes and shapes are good solutions to this differential equation.

Answer 2

on the basis of quantization of energy and angular momentum the electrons revolve around nucleus of an atom.
shape of the orbitals are nothing but an assumption calculated on various quantum mechanical methods.in general strictly out of my possible shape the one which has maximum directional character is supposed to be the real shape of orbital.
this is the reason why from f orbital as the wave equations gets complicated the shape too. and so in most text books you will find shapes only up to d orbital.

Answer 3

The Concept of the electron is that its an electrical micromass which is not static within an atom.
The electron absords or sheds mass in the form of radiation rays.
The orbit of the electron is in the form of planetary motion as outlined by Niels Bohr.However; since the electron mass is not really constant and absorbs external radiation it continually changes and in order to maintain rotational equilibrium around the Nucleous, its orbit is not constant ,and it doesnot move in a two dimensional plane ,but in a three dimensional one.
Therfore ;the electron moving trajectory relative to the Nucleous is not a plane orbit but a elipsoidal orbit. This 3-D motion is called orbital.

Answer 4

Hi. The concept is a lightweight particle with a negative electric charge. They do not move in orbits but rather a cloud that envelopes the nucleus. The cloud changes its size in relation to the amount of energy, but only in discrete quantities.
