    in the nucleus, electrons are negative and are outside the nucleus, while protons are positive and inside the nucleus. |dw:1444426925052:dw| every atom the number of protons = the number of electrons. which means that the elements on the periodic table are neutral. now something happens where you have a charge. if you have a positive charge that means that there are more protons than electrons, called a cation if you have a negative charge that means that you have more electrons than protons. called an anion.

    @theimpossiblegirl54 whenever you have an element that has no charge either + or n - written on top of it, that means that the number of electrons equals the number of protons.

    you can follow along too @blind_Love149 |dw:1444427285494:dw| in the figure above, @theimpossiblegirl54 can you tell me how many protons and electrons this element has?
