SAMPLE PROBLEM 8.7
Writing Electron Configurations and Predicting Magnetic Behavior of Transition Metal Ions
PLAN:
SOLUTION:
(a) Mn2+(Z = 25)
(b) Cr3+(Z = 24)
(c) Hg2+(Z = 80)
Write the electron configuration and remove electrons starting with the ns electrons to attain the ion charge. If the remaining configuration has unpaired electrons, the ion is paramagnetic.
paramagnetic
paramagnetic
not paramagnetic (is diamagnetic)
