Which element is represented by the symbol Cr?

Which element is represented by the symbol Cr?

• A. Calcium
• B. Chromium
• C. Copper
• D. Cobalt

Answer: (B)

Recognizing element symbols on the periodic table is how we identify which element a symbol represents. The symbol Cr corresponds to chromium, a transition metal with atomic number 24. The two-letter format—the first letter uppercase, the second lowercase—is a standard way elements are shown, and Cr matches the name chromium. This helps differentiate it from the other common metals: calcium is Ca, copper is Cu, and cobalt is Co. In welding and metallurgy, remembering chromium is useful because it contributes hardness and corrosion resistance in stainless steels, which is why its symbol is familiar in material specs and charts.
