What is the electron configuration of Cd2+?
1 Answer
Explanation:
Your starting point here will be the electron configuration of a neutral cadmium atom.
Cadmium,
This also tells you that the
So, the electron configuration of a neutral cadmium atom looks like this
#"Cd: " 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 4p^6 4d^10 5s^2#
Alternatively, you can use the noble gas shorthand notation to write cadmium's electron configuration based on that of krypton, the noble gas that comes before cadmium in the periodic table
#"Cd: " ["Kr"] 4d^10 5s^2#
Now, the
Therefore, the electron configuration of the
#"Cd"^(2+): ["Kr"] 4d^10#
