Question

What is meant by duplet rule? What are sub atomic particles? Name them​

Answer 1

Duplet rule :  Having two electrons in the outer valence shell, rather than eight, does not affect the stability of the individual atom, as they have only a 1s orbital, which can hold a maximum of two electrons.

The particles constituting an atom are called sub–atomic particles or elementary particles. There are three sub–atomic particles –protons, electrons and neutrons...
