My question is in regards to Cd2+ and its electron configuration. In its neutral state the configuration is [Kr]4d^10 5s^2. What is it in its 2+ state?
The Attempt at a Solution
The answer is either [Kr] 4d^8 5s^2 or [Kr] 4d^10 5s^0
The difference between these two is taking it from the 5s level and the 4d level. Which one would you take it from?
