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.
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.
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?
To verify the number of electrons in an ion of an element, you can follow these steps:
1. Identify the atomic number of the element, which represents the number of protons in the nucleus. This is usually provided on the periodic table.
2. Determine if the ion has a positive or negative charge. A positive charge indicates that electrons have been lost (resulting in fewer electrons than protons), while a negative charge means that electrons have been gained (resulting in more electrons than protons).
3. Adjust the number of electrons based on the ion's charge. For a positive ion, subtract the magnitude of the charge from the atomic number to get the number of electrons. For a negative ion, add the magnitude of the charge to the atomic number.
4. Verify the total number of electrons by comparing it to the atomic number. They should be the same, assuming there are no errors or exceptional circumstances.
Regarding your wordings, here is a revised version:
To determine the number of electrons in an ion of an element, start by checking the atomic number. The atomic number represents the number of protons, which is also equal to the number of electrons in a neutral atom. However, ions can have a different number of electrons due to a positive or negative charge.
If the ion has a positive charge, it means that electrons have been lost, resulting in a lower number of electrons than protons. Subtract the magnitude of the positive charge from the atomic number to get the number of electrons.
On the other hand, if the ion has a negative charge, it means that electrons have been gained, resulting in a higher number of electrons than protons. Add the magnitude of the negative charge to the atomic number to determine the number of electrons.
Now, let's address the question about an element with 12 protons and 36 electrons:
a) Based on the given information, the element is an ion since the number of electrons (36) is different from the number of protons (12), which would be the case in a neutral atom.
b) The element cannot be determined solely based on the provided information. The number of protons (12) doesn't uniquely identify an element, as several elements can have this same atomic number.
c) To determine the charge of the ion, we need more information. Without knowing the true charge, we cannot accurately ascertain whether it is neutral (no charge), positive, or negative.
Hope this explanation helps, and feel free to ask if you have any more questions!
