Question 6
Click this link to access the Periodic Table. This may be helpful throughoutthe exam. Write the subshell electron configuration (i.e.1s^2 2s^2 , etc.) for the Fe 26 atom (^) and then identify the last electron to fill and write the 4 quantum numbers (n, l, ml and ms) for this electron. Fe 26 = 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^6 : n=3, l=2, ml = - 2, ms = - 1/
