# Problem: Which of the following atoms has the most unpaired electrons?(a) Co (b) Mn (c) V (d) Fe (e) Cr

###### FREE Expert Solution

Determine the # of unpaired electrons by constructing an orbital diagram for each atom

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

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

Step 2: Draw the orbital diagram for the outermost sublevel and determine the number of unpaired electron

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