describe how to verify the # of electrons in the ion of an element.
Can you please correct some of my wordings in here. I don't really get how to explain it.

You look at the atomic number which is the same number of protons as electrons; but if there is a positive ion charge, then that measn that an electron has just been lost so it drops down that number. If there is a negative charge, then the electron moves up its amount; more than protons.

This is another question which I'm kind of having difficulties on:

A certain element has 12 protons & 36 electrons.

a)is the element an atom or an ion?
b)which element is it?
c)what charge, if any, does it have?

For a) I wrote:
The element is an ion because if it were to be an atom, then it would have the same amount of protons as electrons or vice versa.

B, and C I don't really know. I thought that the atomic number would be 12 and the charge would be -2, but I figured not.

All your help will be appreciated, thanks

I think you've just tried to explain too much in one sentence.

You look at the atomic number which is the number of protons and neutrons in the neutral atom. If there is a positive charge on the ion, then that means that electrons have been lost. A negative charge on the ion, then that means electrons have been added. The number of electrons equals the number of protons - (number + charges) for positive ions and the number of protons + (number of - charges) for negative ions.

Of course, this is correct.

Which element is it? Look on your periodic table and see what is in atomic number 12.

What charge is it? It has 12 protons so that is 12 + charges. It has 36 electrons so that is 36 - charges. If I add 12+ and 36- what do I get?
