Answer

Chromium (Cr): 6 unpaired electrons

Work Step by Step

In the ground state, the number of unpaired electrons for each of the first-row transition metals from chromium through zinc are as follows: - Chromium (Cr): 6 unpaired electrons - Manganese (Mn): 5 unpaired electrons - Iron (Fe): 4 unpaired electrons - Cobalt (Co): 3 unpaired electrons - Nickel (Ni): 2 unpaired electrons - Copper (Cu): 1 unpaired electron - Zinc (Zn): 0 unpaired electrons Therefore, the correct answer is: - Chromium (Cr): 6 unpaired electrons
