Solution: Classify each of these ions as diamagnetic or paramagnetic.Cu2+Ni2+Zn2+Co2+

Solution: Classify each of these ions as diamagnetic or paramagnetic.Cu2+Ni2+Zn2+Co2+

Problem

Classify each of these ions as diamagnetic or paramagnetic.

Cu2+

Ni2+

Zn2+

Co2+

Solution

We’re being asked to classify each ion as diamagnetic or paramagnetic.


Recall that for:

• diamagnetic: all of the electrons are paired

• paramagnetic: at least one electron is unpaired


To do so, we need to do the following steps:

Step 1: Determine the shorthand e config. of the neutral element.

Step 2: Determine the e config. of the ion.

Step 3: Draw the orbital diagram for the outermost sublevel and determine if the ion is diamagnetic or paramagnetic


Note that for a neutral element, Atomic Number = # of protons = # of electrons.
