An ion has 12 protons, 14 neutrons, and 10 electrons. the symbol for the ion is

The symbol for the ion is Mg²⁺

From the question given above, the following data were obtained:

Proton = 12

Neutron = 14

Electron = 10

Next, we shall determine the atomic number of the ion.

The atomic number of an element is simply the number of protons in the atom of the element.

Proton = 12

Thus, the ion is magnesium (Mg) ion since only magnesium has atomic number of 12

Finally, we shall determine the charge on the ion. This can be obtained as follow:

Proton = 12

Electron = 10

Charge = Proton – Electron

Charge = 12 – 10

Therefore, the symbol of the ion is Mg²⁺
