Which symbol corresponds to Calcium?

Explanation:
Elements are written with short symbols on the periodic table, usually one or two letters. The first letter is capitalized and a possible second letter is lowercase. This convention makes symbols easy to read and distinguish elements with similar names. For Calcium, the symbol is Ca, using the first two letters of its name. You’ll see it in formulas like CaCO3 (calcium carbonate). Other elements have different symbols, such as potassium = K and argon = Ar, showing how symbols map to specific elements rather than the full names.
