Nimen alkuperä: lot
Nimen tarkoitus: the German word for 'weight', as the element is very heavy, and is used in weights
- in Latin, lead was called plumbum; in Rome, lead was used for plumbing
- is a soft, malleable poor metal, also considered to be one of the heavy metals
- has a bluish-white color when freshly cut, but tarnishes to a dull grayish color when ex
- has a shiny chrome-silver luster when melted into a liquid
- like mercury, another heavy metal, lead is a potent neurotoxin that accumulates in soft tissues and bone over time
- is used in building construction, lead-acid batteries, bullets and shot, weights, and is part of solder, pewter, fusible alloys and radiation shields
- has the highest atomic number of all stable elements, although the next element, bismuth, has a half-life so long (longer than the estimated age of the universe) it can be considered stable
