Lead:
Atomic number
82
Symbol
Pb
Atomic weight
207.2
Discovery
Known since prehistoric time
Electronic configuration
6p2
Properties:
1. It is a heavy, soft and malleable metal with blue gray colour.
2. It shows a metallic luster when freshly cut but it gets oxidized soon.
3. It can be easily rolled into sheets and pipes or can be extruded to form pipes but cannot be cut into fine wires.
4. It is corrosion resistant.
Uses: Lead is used of the manufacturing of plates of storage batteries. It is used in covering electric cables. It is used as lead accumulators. Tin lead-alloy is used for soldering wires.
Radiation and Radioactivity Investigator of radioactivity discovered that certain natural elements, primarily the very heavy ones, have unstable nuclei that disintegrate to emi
The discharge over a triangular notch can be written as Q = (8/15) Cd (2g)0.5 tan(θ/2) H5/2 If an error of 1% in measuring H is introduced determine the corresponding error
A girl throws a 0.1 kilogram ball at a wall. The ball hits the wall perpendicularly with a velocity of 5 meters per second and then bounces straight back with a velocity of 4 mete
how to solve A • B x C = A x B • C?
(Assume the metallic ball is spherical with a diameter d = 2.5 cm. Let''s also assume it is made out of nickel, which has a density of roughly 9 g/cm 3 .) After it first touches
