What are
the Properties of Lead? Definition of Lead
What is the definition of
Lead? It is a soft, malleable, ductile, bluish-white, dense metallic element,
extracted chiefly from galena and used in containers and pipes for corrosives,
solder and type metal, bullets, radiation shielding, paints, and antiknock
compounds. Lead is a relatively poor conductor of electricity. It is very
resistant to corrosion but tarnishes upon exposure to air. The
Physical and
Chemical Properties are the
characteristics of a substance, like Lead, which distinguishes it from any
other substance. Most common substances, like Lead, exist as
States of Matter as solids, liquids, gases and plasma. Refer to the article on
Lead for additional information and facts about this substance.

What are the Physical
Properties of Lead? The Physical properties of Lead are the characteristics
that can be observed without changing the substance into another
substance. Physical properties are usually those that can be observed using our
senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor. The Physical Properties of Lead are as follows:

Lead Properties - What are the Chemical Properties of Lead?
What are the Chemical
Properties of Lead? They are the characteristics that
determine how it will react with other substances or change from
one substance to another. The better we know the nature of the substance the
better we are able to understand it. Chemical properties are only observable during a
chemical reaction. Reactions to substances may be brought
about by changes brought about by burning, rusting, heating, exploding, tarnishing
etc. The Chemical
Properties of Lead are as follows:
Lead is a
moderately active metal. It dissolves slowly in water and in most cold acids. It
reacts more rapidly with hot acids. It does not react with oxygen in the air
readily and does not burn.
