What is the correct electron configuration for the ion, Mo2+? Question 17 options: [Kr] 5s2 4d2 [Kr] 4d4 [Kr] 5s2 4d6 [Kr] 4d6 [Kr] 4d5
Which electron configuration is correct for Sn4+? A. [Kr]4d10 B. [Kr]5s2 4d8 C. [Kr]5s2 5d8 I know that the answer is A, but can someone explain why it doesn't go in the order of [Kr] 5s2 then 4d10 ?? (Therefore being answer B) The quantum numbers for 3 and 4 go in the order 3s2 3p6 4s2 then 3d10 Why wouldn't this be the case for this problem? Please help!

Electron Configuration PRACTICE: This question is worth ZERO POINTS. (Use this question to make sure that you understand the proper format for entering electron configurations) Enter your answer with subshells in increasing energy order, without superscripts and with spaces between subshells and after the closing square bracket. Example: vanadium (V) Electron configuration: 1s 2s 2p°3s 3p°4s 3d* Abbreviated Configuration: [Ar]4s 3d Entered the configuration as: [Ar] 4s2 3d3 Practice (IF YOUR ANSWER IS INCORRECT,_place your mouse pointer over the answer...
