2A.7 in the textbook

[Jacqueline Duong 1D]

Hi, I had a question on 2A.7 in the textbook:
The following species have the same number of electrons: Cd, In+, and Sn 2+.(a) Write the electron configurations for each species. Explain any differences. (b) How many unpaired electrons, if any, are present in each species? (c) What neutral atom, if any, has the same electron configuration as that of In 3+?

My question was specifically on part (c). The electron configuration of In 3+ would be [Kr] 4d^10, and the answer at the back of the book is Pd. While that makes sense, I wanted to clarify that if we lose the valence electrons in the 5s subshell (in this example), we should just shift the valence electrons in the 4d subshell over?

Sorry for the long question, I hope it makes sense!

Thanks in advance!!

The answers [Kr] 4d10 and Pd are given as equivalents. When you take 3 electrons away from In (49), you end up with (46) which is Pd.
