The symbol Hg is the chemical symbol for which element, derived from its Latin name hydrargyrum?

Explanation:
Chemical symbols are often derived from older or Latin names rather than the English name. Hg comes from hydrargyrum, the Latin name for mercury. Hydr- means water and argyros (from Greek) means silver, reflecting mercury’s liquid, metallic appearance. Because of that Latin origin, the symbol Hg is used for Mercury, not the English name. The other elements mentioned have symbols that match their English names or their standard Latin-derived forms (Helium → He, Magnesium → Mg, Manganese → Mn).
