Lithium is a metal whose electronic configuration is 2 and 1 including 3 protons 3 electrons and 3 neutrons. So, if we remove 1 electron from lithium to make it stable. Then ,why would we call it lithium as it has 3 protons 3 electrons and 3 neutrons. But , after removal of 1 electron only 2 electrons are left. So, why would we call it lithium then.
Octet rule states that elements tend to combine in such a way that each atom has eight electrons in its valence shell. Why only 8 electrons?
