What element has the symbol 'Pb'?

The story behind the answer

Pb is the symbol for Lead because it comes from the Latin name plumbum. That root appears in words like plumbing and plumb line, reflecting lead’s historical use in pipes and weights. Lead is a heavy, soft metal with a low melting point; once common in paints and gasoline, it’s now tightly regulated due to toxicity.
