The spin only magnetic moment of a divalent ion in aqueous solution (atomic number 29) is  BM

Canvas Classes · Accepted Answer

Strategy:
 Identify the metal based on its atomic number, determine its divalent electron configuration, state the number of unpaired electrons in an aqueous complex, and extract the magnetic moment.

Step 1: Identify the metal
Atomic number 29 corresponds to Copper (Cu).
The divalent ion is .

Step 2: Identify unpaired electrons
Copper configuration: .
 configuration: .
A  system will always have completely filled lower orbitals and 1 unpaired electron regardless of the field.
Unpaired electron
