Question

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

<b>I think you've just tried to explain too much in one sentence.</b>

<b>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.</b>

<b>Of course, this is correct.</b>

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

<b>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?</b>
