Answer:

the net charge of that ion is +2

Explanation:

  • An ion has electron, proton and neutron.
  • Electron and proton are negatively and positively charged respectively.
  • But, neutron is neutral thus has no charge.
  • The ion that has 11 proton and 9 electrons, the 9 electrons will be balanced by the 9 protons and remaining two protons will be the net charge of the ion.
  • So, the net charge of ion will be +2 in that ion.
