The Scientific Aspect

"...an atom or molecule with a net electric charge due to the loss or gain of one or more electrons." -google

        Ions are basically just atoms that have too many or too little of either protons or electrons. If you were an atom with more protons than electrons, you would no longer be an atom, but a positively charged Ion, opposing a negatively charged atom, which would be if you had more electrons than protons. Protons and electrons need to be equal for the state of an atom to be neutral, AKA 'normal'. So why are neutrons there? Lets say you had one ear. Ears are needed for a state of balance on the human body, which means you might have to try a little harder to stay upright and move straight, however, you can still survive, and hear for that matter. The neutrons are there to even out the weight difference within the atom, and they are present in every element except for ordinary hydrogen, which only has one proton and one electron. Positively charged ions can sometimes take away bits of static electrons floating around, like when you touch a doorknob and shock yourself. Negatively charged ions usually can't rip the nucleus of other atoms apart to find more protons, however, they can pass on some of their electrons to a positively charged ion and not expect any in return. Ions can be created, or rather, atoms can be disequalized, usually by scientists, geneticists, or some kind of physicists, by way of ionization, which involves taking the electrons from an atom (taking a conductive/magnetic material to it to force the atom to pass on electrons).
