I have chem problems here that are asking me to tell how many electrons there are in the nucleus of a given ion. Ex: How many in a chloride ion? I don't know how to do this and it just doesn't seem to be "clicking" Could someone please give me an example? Thanks!!!

There are no electrons in the nucleus; it is only comprised of neutrons and protons.
To determine how many electrons there are in the ATOM or ion as a whole, look up the atomic number of the element, (e.g. chlorine is 17), then add the additional electrons it has (chlorine exists as Cl- when ionic. so it has a -1 charge (1 extra electron). 17 electrons + 1 = 18 electrons on a chloride ion)

There are no electrons in the nucleus of any chloride ion. In particular, there are 17 protons in the nucleus of any chlorine atom. There are either 18 or 20 neutrons in any stable chlorine atom. There are 18 electrons circling any chloride ion.
