Etymology

Description

It is a heavy, ductile and leaden colored element belonging to group 14. It is used in construction, lead batteries, bullets and pellets. It is used in solder, lead-tin alloy, bearing and scrap metals and easily melting alloys.

Language Of Origin

Old English

Origin Of Word

From the English word (from Latin plumbum)

Etymological Description

The symbol Pb is the abbreviation of plumbing, which means "lead craftsmanship", "lead work", which is translated into English through the Latin plumbum.
