What are Alkali Metals? Define Alkali Metals
Alkali Metals are used as a term in
Periodic Chemistry when classifying the chemical elements. Each element can usually
be classified as a metal or a non-metal based on their general
Physical and Chemical Properties. These metals are any of the metallic elements within
Group 1 in the Periodic Table (see the List of Alkali metals). They are soft
metallic elements that form alkali solutions when they combine with water.
The alkali metals have one electron in their outer shell, and therefore
react easily with other elements and are found in nature only in compounds -
see Examples of Compounds.
What are Alkali Metals? Common Properties of Alkali Metals
Alkali metals are soft, malleable,
ductile, and are good conductors of heat and electricity. They are very
reactive metals that do not occur freely in nature. Except for cesium, which
has a gold sheen, alkali metals are white.
Nearly 75% of all the elements in the Periodic Table are classified
as metals which are detailed in the
List of Metals.
Elements classified as Alkali Metals
The 6 elements classified as "Alkali Metals" are located in
Group 1 elements of the Periodic Table. Elements classified as Alkali Metals
are therefore any of a group of soft, low-density, low-melting, highly
reactive metallic elements which are powerful reducing agents. Except for
cesium, which has a gold sheen, alkali metals are white. They have one
electron in their outer shell, and therefore react easily with other
elements and are found in nature only in compounds. The alkali metals form
alkali solutions when they combine with water (especially when heated). When
combined with water Alkalies form strongly basic solutions with an acrid
taste.
