What are
the Properties of Gold? Definition of Gold
What is the definition of
Gold? It is
a soft, yellow, corrosion-resistant
element, the most malleable and ductile metal, occurring in veins and alluvial
deposits. A good thermal and electrical conductor, gold is generally alloyed to
increase its strength. The
Physical and
Chemical Properties are the
characteristics of a substance, like Gold, which distinguishes it from any
other substance. Most common substances, like Gold, exist as
States of Matter as solids, liquids, gases and plasma. Refer to the article on
Gold for additional information and facts about this substance.
Gold Properties
- What are the Physical Properties of Gold?
What are the Physical
Properties of Gold? The Physical properties of Gold 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 Gold are as follows:
|

Gold Properties - What are the Chemical Properties of Gold?
What are the Chemical
Properties of Gold? 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 Gold are as follows:
|
What are the Chemical Properties of Gold? |
| Chemical
Formula |
Au |
| Activity |
Gold is chemically inactive,
it's extremely resistant to chemical action |
| Compounds |
Ready reducibility from
compounds to metal.
Auric chloride and
chloro-auric acid are its most common compounds. |
|
Reactivity with acids |
Aqua regia, a mixture of
nitric and hydrochloric acids, has the ability to dissolve gold |
| Isotopes |
It has one stable isotope,
197Au |
|
Reactivity with Non-metals |
Gold does not react with
the Non-metals, except for halogens, with which it forms halides
|
| Alloys |
Silver and platinum |
