We can answer this question by writing the electron configuration of each ion, then choose the ones that have six electrons in the outermost d level. The number of electrons in the neutral atom can be known from the periodic table and the number at the side of the positive sign on the ion indicates the number of electrons the atom lost (so you can calculate the number of electrons of the ions easily).I hope that these ions are your options:(1) Os^2+:We have the following configuration: [Xe] 4f^14 5d^6(2) Ru^2+:We have the following configuration: [Kr] 4d^6(3) Zn^2+:We have the following configuration: [Ar] 3d^10 (4) Mn2+:It has the following configuration: [Ar] 3d^5 (5) Tc^2+:We have the following configuration: [Kr] 4d^5 (6) y^2+:We have the following configuration: [Kr] 4d^1 (7) Fe2+: We have the following configuration: [Ar] 3d^6From the above configurations, the right decisions are:I^2+Ru^2+Fe2+
