text: what is the number of electrons in kryton?   krypton has 36 electrons.  it's atomic number is 36 which means it has 36 protons.  because atoms have the same number of electrons (negative charges) as they do protons (positive charges) then it must also have 36 electrons.  don't get atoms confused with ions - an ion is an atom that has a positive or negative charge... meaning that it has more or less electrons than it does protons.  an atom can't have more or less protons without it becoming something else.  if krypton had one more proton it would be rubidium, if it had one less it would be bromine.  by the way, kryton (or kryten) was a character in the tv series red dwarf and he would have had squillions of electrons.
