There are six unpaired electrons in atoms of elementZ. What could element Zbe? A. sulfur B. iron C. carbon D. chromium

## Step 1The problem is asking us to identify an element that has six unpaired electrons. To solve this, we need to understand the electron configuration of each element listed in the options.## Step 2### **Sulfur (S)**Sulfur has an atomic number of 16. Its electron configuration is . In the 3p orbital, there are two electrons with opposite spins, making them paired. Therefore, sulfur does not have six unpaired electrons.## Step 3### **Iron (Fe)**Iron has an atomic number of 26. Its electron configuration is . In the 3d orbital, there are six electrons, but they are not all unpaired. Iron has four unpaired electrons in the 3d orbital.## Step 4### **Carbon (C)**Carbon has an atomic number of 6. Its electron configuration is . In the 2p orbital, there are two electrons with opposite spins, making them paired. Therefore, carbon does not have six unpaired electrons.## Step 5### **Chromium (Cr)**Chromium has an atomic number of 24. Its electron configuration is . In the 3d orbital, there are five electrons, and in the 4s orbital, there is one electron. Chromium has six unpaired electrons in total.Based on this analysis, the element with six unpaired electrons is chromium.
