A monotomic ion has a charge of +2. The nucleus of the parent atom has a mass number of 55. If the number of neutrons in the nucleus is 12 times that of the number of protons, what is the chemical symbol of this element?

The charge on the ion has no bearing on what is in the nucleus.
It is impossible to have 12 times the number of protons, than neutrons.
If the mass of the atom is 55, then the atom is manganese. Mn, 25 protons, 30 neutrons. The ion Mn+2, so 2 e- have left

A nucleus where the number of neutrons is 12 that of protons is impossible not stable!
