What is the chemical symbol for lead?

The correct answer is: Pb

The chemical symbol for lead is Pb, which is derived from the Latin word "plumbum." This symbol is used universally in the periodic table to represent the element lead. Understanding the origin of the symbol helps in recognizing its historical context, as many chemical symbols are based on Latin names. The other options do not correctly represent lead; Ln does not correspond to any known element, Pb2 suggests a compound rather than a singular element representation, and Li is the symbol for lithium, another distinct chemical element. The correct symbol Pb is integral in discussions of lead-related regulations and health risks, particularly in the context of lead-based paint and its implications for environmental safety.
