Homework Help: Chemistry - electron configuration

Posted by Constantine on Friday, April 19, 2013 at 8:24pm.

Hello Dr.Bob. Could you please take a look at the following question? I know the correct answer for it, but I'm not sure how to go about solving it.

Which ground state electronic configuration will most readily ionize to a 2 + cation?

A) 1s22s22p63s23p64s23d10
B) 1s22s22p63s23p64s23d104p4
C) 1s22s22p63s23p64s1
D) 1s22s22p63s23p64s23d104p2
E) 1s22s22p63s23p2

The correct answer for this question is A). Could you please let me know why that configuration is the right one? I thought that since A) has a complete outer electron shell, then it would be more stable and thus less likely to ionize to a 2+ cation.
