What are Alkaline Earth Metals? Define Alkaline Earth Metals
Alkaline Earth 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 2 in the Periodic Table (see the List of Alkaline
metals). The name Alkaline Earth Metals refer to their oxides that simply
give basic alkaline solutions. They are reactive and widely distributed in
rock structures.
What are Alkaline Earth Metals? Common Properties of Alkaline Earth Metals
Alkaline metals are usually shiny solids
that conduct heat or electricity and can be formed into sheets. With the
exception of beryllium and magnesium, the metals have a distinguishable
flame color, orange for calcium, bright red for strontium, green for barium
and crimson red for radium. Nearly 75% of all the elements in
the Periodic Table are classified as metals which are detailed in the
List of Metals.

properties in common:
-
Shiny

Alkaline Earth Metals List - Chemical Elements in the Periodic Table
The elements contained in
the classification of Alkaline Earth Metal list are as follows:
Elements classified as Alkaline Earth
Metals
The 6 elements classified as "Alkaline Earth Metals" are
located in Group 2 elements of the Periodic Table.
Elements classified as Alkaline Earth Metals are all
found in the Earth’s crust, but not in the elemental
form as they are so reactive. Instead, they are widely
distributed in rock structures.
