There are three kinds of forces within the atom:

  i) Electromagnetic force of attraction between the electrons and protons

  ii) Electromagnetic force of repulsion between the protons or weak nuclear force

  iii) Strong nuclear force between the electrons and protons

<h3>What is nuclear force?</h3>

The electromagnetic force of attraction:

  • Electrons circle in the orbits above the nucleus. There exists an electromagnetic force of pull between the electrons and protons. That’s why electrons do not depart the atom.

Weak nuclear force:

  • It is an electromagnetic significance of revulsion between the protons in the nucleus of the atoms.

Strong nuclear force:

  • This force is strongest from all the fundamental details and exists between the protons and neutrons in the nucleus of an atom. This pressure overcomes the weak nuclear force and does not allow protons to stray out.
