Question

I don't understand what they are asking.
4 protons, 2 electron
Express your answer as an ion.

Answer 1

if an atom had been formed with 4 protons and 2 electrons, what would its elemental symbol be with what charge.

Answer 2

say an atom was formed with 1 proton and 2 electrons

1 proton in the nucleus is always a Hydrogen atom.

if it had 2 electrons, it would have 2 negative charges.

since the proton is positive, the total charge would be a negative one (+1 and -2)

therefore its ion would be H^-

what element has 4 protons, and if it had only 2 electrons what would its charge be

**note that charge is written as a superscript, that is as an exponent**

Answer 3

Oh! Okay I understand...thank you!
