Solution: Select the diamagnetic ion.a. Mn2+b. Fe3+ c. P-d. Co2+e. Ni2+f. V3+g. O-h. Cu+i. Mg+

Solution: Select the diamagnetic ion.a. Mn2+b. Fe3+ c. P-d. Co2+e. Ni2+f. V3+g. O-h. Cu+i. Mg+

Problem

Select the diamagnetic ion.

a. Mn2+
b. Fe3+ 
c. P-
d. Co2+
e. Ni2+
f. V3+
g. O-
h. Cu+
i. Mg+

Solution
  • Recall that a diamagnetic ion has no unpaired electrons. 

  • So we need to analyze the orbitals via the electron configuration of each atom:
