So, if other electrons are between a valence electron and the nucleus, the valence electron will be less attracted to the nucleus. That’s called shielding. 3. Complet ...

Introduction to Nuclear Forces

It is well known that in quantum electrodynamics the electromagnetic field is considered jointly with the particles (photons) associated with it. The field as if consists of photons which are the quanta of thi ...
