What are
the Properties of Helium? Definition of Helium
What is the definition of
Helium? It is
a colorless, odorless inert gaseous element occurring in
natural gas and with radioactive ores. It is less soluble in water than
any other gas. The
Physical and
Chemical Properties are the
characteristics of a substance, like Helium, which distinguishes it from any
other substance. Most common substances exist as
States of Matter as solids, liquids, gases and plasma. Refer to the article on
Helium for additional information and facts about this substance.

- What are the Physical Properties of Helium?
What are the Physical
Properties of Helium? The Physical properties of Helium 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 Helium are as follows:
|
What are the Physical Properties of Helium? |
| Color |
|
| Phase |
Gas
When cooled it condenses to liquid helium. Liquid helium is the only
element that does not solidify at normal pressure regardless of the
temperature |
|
Density |
Helium is less dense than
any other known gas except hydrogen and is about one seventh as
dense as air |
| Color |
Colorless |
| Odor |
It is odorless |
|
Viscosity |
Extremely low viscosity
(resistance to flow - stickiness) |
| Taste |
Tasteless gas |
| Compounds |
Helium is completely inert.
It does not form compounds or react with any other element |
Helium Properties - What are the Chemical Properties of Helium?
What are the Chemical
Properties of Helium?
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 Helium are as follows:
