Mo stands for which element?

Mo stands for which element?

• A. Molybdenum
• B. Manganese
• C. Silicon
• D. Tin

Answer: (A)

Mo in the periodic table is the symbol for molybdenum. Each element has a one- or two-letter symbol, and Mo specifically denotes molybdenum, a transition metal with atomic number 42. The other options have different symbols: manganese is Mn, silicon is Si, and tin is Sn, so none of them use Mo. In welding contexts, molybdenum is important as an alloying element in certain steels to boost strength and high-temperature performance, which is one practical reason you might encounter its symbol in practice questions.
