WebMar 6, 2024 · To determine how many electrons are left, subtract the amount of charge from the atomic number. In this case, there are more protons than electrons. For example, Ca 2+ has a +2 charge, therefore, it has 2 fewer electrons than a neutral calcium atom. Calcium’s atomic number is 20, therefore this ion has 18 electrons. 3 WebAug 26, 2015 · Now, one can do it fairly easily with an ion accelerator and a magnet. With the right set up, one can get a beam of mono-energetic ions out of the accelerator, send them through a stripper to remove electrons, and then send them through a magnet to separate the components out by velocity (which depends on the ion mass through the energy).
