What is the chemical symbol for silver?

The chemical symbol for silver is "Ag," which is derived from the Latin word for silver, "argentum." This historical naming convention is common in chemistry, as many elements have symbols that relate to their names in ancient languages. Silver is a precious metal known for its high conductivity, malleability, and antibacterial properties, making it valuable in various applications, including electronics, jewelry, and coinage. The other options represent different elements: "Au" is the symbol for gold, "Si" stands for silicon, and "Pb" is the symbol for lead. Each of these symbols correspond to elements that have their unique properties and uses. Thus, the correct identification of "Ag" reflects an understanding of both the periodic table and the historical context of element naming.
