Question

Which of the following ions have noble gas electron configurations? (Select all that apply.) Y3+, Mn4+, Fe3+, v2+ (a) Y3+ Mn4+ Fe3+ v2+ (b) TI, TI3+, o2- TI+ TI3+ 02- (c) Mo4+, Al3+, Ce4+ Mo4+ A13+ Ce4+ (d) Ba2+, Pd4+, Au3+ Ва2+ Pd4+ Au3+

Answer 1

The complete detail step wise explanation is given as below:-

Part @Electronic configunation Yriu ig given by- 5 se 4d Ck Than k4d 5s 1 K a no ble gay and havin whene, ato mic nuumb en a Kn 36 atomic numb en a Y So, y3+ have the noble aas electro nic Configunation. 39

And Mn = CA 3 d 5 us2 A 3d3 45 noblegayAn) on doeg not Rave the noble gag onfigunotion So Mnt ato mic numb en mn=25 and An 18 = CABa Cs CEe CFe LA 3d5 electonic So, Fest doegnot have the noble gas Con figunation 26 Ato mic mb en a Fe =

LA 3d3 4s2 CA 3d3 4s Vzt does not have the moble Configur ation atomic mumb en al v =23 el ectronic So1 gas So, the conect option wiel be a y3+

Parut (b wehave T e ufi 5dlo 6s2 6Pl = xe ufi 5dlo 6s 6po xe 4f5dl 65 CP CT ETt have Se and T3t gas electoonic Configunation. only o2 have the noble gas electro nic Con figunati on. T Cato miC numben the noble does not = 8 ato mic numb en a Ne = 1o and ox4grn 8 So the Corectophon wilbe 3 02-

PantO we have Cma= 1 mt So, madoes not have dhe hoble gas Configun K4d3 5s electronic ation 3s2 3P Ne 3s23P) CARJ CA1+ So, (AR]3t have tha moble gas 3s 3P electronicanfigunation Ee uf sd6s2 xe 4fsd 65

so [cet have the noble gas electronic Con figunation, So,the cons1ect optiong wiel be 3 Ce4t and AL3+ atromic numb en aCe atominumb en a kn= 5 8 whene, 36 a Ae 13 cMou2 ato micnumb en ato mic nmben
