What are
the Properties of Calcium? Definition of Calcium
What is the definition of
Calcium? It is a
silvery, moderately hard metallic
element that constitutes approximately 3.5% of the earth's crust and is a basic
component of most animals and plants. It occurs naturally in limestone, gypsum,
and fluorite. The
Physical and
Chemical Properties are the
characteristics of a substance, like Calcium, 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
Calcium for additional information and facts about this substance.

What are the Physical
Properties of Calcium? The Physical properties of Calcium 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 Calcium are as follows:

What are the Chemical
Properties of Calcium?
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 Calcium are as follows:

Formula |
Ca |
|
Oxidation |
Used as a deoxidizer in
steel |
| Isotopes |
Six |
| Compounds |
Compounds include
limestone, marble, and gypsum |
|
Flammability |
When heated in air or in
oxygen it ignites |
|
Reactivity with water |
Reacts with cold water
rapidly at first, but the reaction is then slowed due to the
formation of a film of Calcium hydroxide - Ca(OH)2. |
|
Reactivity with acids |
Highly reactive |
