Sn2+

Your protons equal the atomic number of an element: Sn (Tin).

The amount of protons and electrons will be the same if the atom is neutral. In this case, tin has lost two electrons and so tin is no longer neutral and becomes Sn2+

To double check, you would subtract the atomic number from the mass number of tin to see if the number of neutrons is equal to what has been provided.

mass number - atomic number = number of neutrons
118 - 50 = 68

The symbol for the ion having 50 protons, 48 electrons and 68 neutrons is Sn²⁺

Definition of ion

An ion is an atom or a group of atom which possess an electric charge

How to determine the charge of the ion

  • Proton = 50
  • Electron = 48
  • Charge =?

Charge = proton – electron

Charge = 50 – 48

Charge = +2

How to determine the symbol for the ion

  • Proton = 50
  • Electron = 48
  • Charge = +2
  • Atomic number = proton = 50
  • Symbol =?

The atomic number of the ion is 50. Comparing the atomic number of the ion (i.e 50) with those in the period table, the ion is simply an atom of Tin (Sn).

Therefore, the symbol for the ion is Sn²⁺
