Question

Select the ion.

a) NO2
b)H2SO4
c) Al+3 ...?

Answer 1

i would go with C. Al+3

Answer 2

I believe the correct answer from the choices listed above is the third option. The ion would be Al+3. It is obvious because among the options, this is the only substance that has a charge. An ion is an atom or a molecule in which the total number of electrons is not equal to the total number of protons, giving the atom or molecule a net positive or negative electrical charge.
