Which chemical element is represented by the symbol Cr?

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

Answer: (A)

In chemistry, each element has a unique symbol used on the periodic table and in formulas. The symbol Cr identifies chromium. It comes from the element’s name, typically the first one or two letters, so Cr matches the start of “chromium.” Some elements use symbols from Latin roots or older spellings, which is why you see other symbols like Ca for calcium, Cu for copper (from cuprum), or Co for cobalt. So Cr is the label for chromium, distinguishing it from the others listed.
