We’re being asked to determine which ions have noble gas electron configurations.
For this, we shall do the following:
Step 1: Find the number of electrons in the ions.
Step 2: Check the number of electrons against the noble gases in the periodic table.
The noble gases in the periodic table are:
Which of the following ions have noble gas electron configurations?
a. Fe2+, Fe3+, Sc3+, Co3+
b. Tl+, Te2—, Cr 3+
c. Pu4+, Ce4+, Ti4+
d. Ba2+, Pt2+, Mn2+
