ANSWER:
SolutionWe have been asked to write the electronic configurations and determine the ions that havenoble-gas configurations.Step 1A point to be noted is that electrons are always removed from the outermost orbital in an atom. Element Atomi Electronic Ion Electronic Noble gas with the same c configuration of configuration electronic configuration numbe atom of the ion as that of ion r Co 27 [Ar]3d 4s Co2+ [Ar]3d7 No noble gas with same configuration Sn 50 [Kr]4d 5s 5p2 Sn+ [Kr]4d 5s 2 No noble gas with same configuration Zr 40 [Kr]4d 5s Zr+ [Kr] Krypton 10 1 + 10 Ag 47 [Kr]4d 5s Ag [Kr]4d No noble gas with same configuration S 16 [Ne]3s 3p4 S- [Ne]3s 3p6 Argon
