Definition
of the lead element
of the lead element
A soft
malleable dustile, bluish – white dense
material element extracted chiefly from galena and used in container and
pipes to corrosives solder and type
metal, bullets, radiation shielding, paints and antiknock compound lead is a
relatively poor conductor of electricity it is very resistant to corrosion but tarnishes upon exposure to air the atomic
number symbol is Pb.

Origin/meaning of the name lead
The English
name lead is cleaved from the celtic word “luaide” meaning reddish, because of
the odor of red lead, or lead, or lead tetroxide. Red lead was prepared by
hating white lead to a very high temperature. It was used as a pigment in the
production of used in painting and particular for illumining manuscripts

Origin/meaning
of the symbol for lead (Pb)
of the symbol for lead (Pb)
The symbol
for lead Pb originates from the word
plumbum which is the latin name for lead. A roman worker in lead was
called a plumbarious, hence the name
plumber which started to be used in the lath century when lead water pipes
became the principle work of the trade, plumbise is the medical term for lead
poisoning.

Periodic
table group and classification of the lead element
table group and classification of the lead element
Element
can be classified based on them physical states (states of matter) e.g gas
solid, or liquid this element is a
solid. Lead is classified in the other
metals section which can be located in group b, 14 and 15 of the periodic table
all of these elements are solid, have a relative high density and are opaque.
In a general overview of the element we can at first describe lead as a solid
it is a bluish metallic element which is
seldom found uncombined in nature,
however a compound of lead called
galena, is widely distributed the chief producers of lead are the U.S.A,
Australia and Canada. Nearly 75% of all the elements in the periodic table are
classified
