What is the Electron Configuration of Cd2+?

AI Thread Summary
The electron configuration of Cd2+ is debated, with two possible configurations proposed: [Kr] 4d^8 5s^2 and [Kr] 4d^10 5s^0. The discussion centers on whether electrons are removed from the 5s or 4d subshell. It is suggested that the 5s electrons are typically removed first due to their higher energy level in the context of ionization. Ultimately, the consensus leans towards [Kr] 4d^10 5s^0 as the more likely configuration for Cd2+. Understanding the energy levels of these subshells is crucial for determining the correct electron configuration.

Homework Statement



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?


Homework Equations





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?

How do you think, which ones have lower energy and are easier to remove?
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
