Why does losing gaining an electron cause the other element to gain lose atoms?
Why does losing gaining an electron cause the other element to gain lose atoms? Answer: A positive ion is formed where an atom has more protons than electrons. Atoms and chemical species lose or gain electrons when they react in order to gain stability. Thus, typically, metals (with nearly empty outer shells) lose electrons to […]
