Well, for iodine...#Z=53#...

Explanation:

Why is the atomic number significant for this question...

The number of protons, is EQUAL to the number of electrons in the NEUTRAL atom...and so we follow the usual #"Aufbau scheme.."#

#underbrace(1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)4s^(2)3d^(10)4p^(6)5s^(2)4d^(10)5p^5)_"53 electrons as required..."#
