List all the orbitals in each principal level. Specify the three quantum numbers for each orbital.
a. n = 1
b. n = 2
c. n = 3
d. n = 4
Solution Step 1 Here we have been asked to find the neutral atom that has the same configuration as that of ion.The configurations are as given in the table. Step 2 Neutral element Ion formed-Its atomic no: Neutral Electronic Comparison (atomic no:) and and electronic atom with configuration of of electronic configuration same the neutral atom Configuration configuration atomic s (1) number as (4) (comparing (2) that of ion (2) and (4)) (3) Cl-17-[Ne]3s 3p 5 Cl (18)- [Ne]3s 3p 6 Ar [Ne]3s 3p 6 Same Sc-21-[Ar]4s 3d 1 Sc (18)-[Ne]3s 3p 6 Ar [Ne]3s 3p 6 Same 2 6 2+ 6 4 2 Fe-26-[Ar]4s 3d Fe (24)-[Ar]3d Cr [Ar]3d 4s Different Zn-30-[Ar]4s 3d 1 Zn (28)-[Ar]3d 10 Ni [Ar]3d 4s 2 Different 0 Sn-50-[Kr]5s 4d 1 Sn (46)-[Kr]4d 10 Pd [Kr]4s 3d 8 Different 05p2
