Solution: Of the first row transition elements listed below, which is or are diamagnetic?(1) Ti (#22)        (2) Fe (#26)        (3) Zn (#30)a. (1) and (2) onlyb. (1) and (3) onlyc. (2) and (3) onlyd. only (1) OR only (2) OR only (3)e. (1), (2) and (3) - all three

Construct the electron configuration of the valence electrons of each atom given and determine which is diamagnetic

To find the diamagnetic element, we must find the orbital diagram with no unpaired electrons. Filling up the electrons before the valence electrons where all of the electrons in lower energy orbitals are paired.
