How is shielding effect explained?

1 Answer

The electrons situated far from the nucleus feel a smaller attraction because of the electrons between them and the nucleus.

Explanation:

The shielding effect is the decrease in attraction between an electron and the nucleus that is caused by the other electrons in the atom.

The electrons between an outer electron and the nucleus cancel some of its charge.

Thus, the nucleus can't attract the outer electrons with its full charge.
