element lead?

Question

tell me everything you know about the element lead.

Answer 1

This is not everything, just lead trivia

Pb can form inorganic salts and chelated compounds. You probably do not remember leaded gasoline. The lead was in the form of tetraethyl lead, a covalently bonded lead compound.

Workers with potential exposure to lead fumes have been known to perform "prophylactic chelation". They get an injection of a chelating substance like EDTA prior to being exposed to lead fumes so as to remove lead from their blood before it can get involved in harmful metabolism.

Answer 2

That would be a tall order! Look in any good chemistry book or online. Lead is a heavy metal with a high density. Lead by the way is the stable final element formed by the radioactive decay of uranium.

Answer 3

Name: lead
Symbol: Pb
Atomic number: 82
Atomic weight: 207.2 (1) g/ mole
Group number: 14
Period number: 6
Block: p-block
Standard state: solid at 298 K
Colour: bluish white
Chemical series: poor metals

Lead is a bluish-white lustrous metal. It is very soft, highly malleable, ductile, and a relatively poor conductor of electricity. It is very resistant to corrosion but tarnishes upon exposure to air. Lead pipes bearing the insignia of Roman emperors, used as drains from the baths, are still in service. Alloys include pewter and solder. Tetraethyl lead (PbEt4) is still used in some grades of petrol (gasoline) but is being phased out on environmental grounds.

Lead isotopes are the end products of each of the three series of naturally occurring radioactive elements.
