Question

What charge would be associated with an iron atom that had 37 electrons?

Answer 1

Why....`-11`

Explanation:

We got 37 fundamental, negative charges, and 26 fundamental, positive charges. The net charge is the difference `26-37=-11`.

The number of neutrons was there to distract you, as these are neutrally charged fundamental particles....

And we can go farther that this and specify the isotope.

We have `""^43Fe^(-11)`....not that we would have any chance of observing such an ion. Such a charge at an atomic level is pretty absurd.
