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 Chemical and Physical 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.

The elements classed as "Alkaline Earth metals" have the following properties in common:

Shiny Solids
Two electrons in the outer shell
Can conduct heat or electricity
Can be formed into sheets

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.

Elements in the Periodic Table are classified as follows:

Metalloids
Alkali Metals
