Periodic Table Group 2A Elements Flashcards

Study Notes

Alkaline Earth Metals

Group 2A of the periodic table comprises alkaline earth metals.
These elements are known for their high reactivity, though lower than alkali metals (Group 1A).

Beryllium (Be)

Beryllium is a hard, grayish metal.
It has a very high melting point and is used in aerospace and nuclear applications due to its lightweight properties.

Magnesium (Mg)

Magnesium is a shiny gray metal known for its low density.
It is commonly used in alloys, fireworks, and the production of several chemical compounds.

Calcium (Ca)

Calcium is a vital element for living organisms, particularly in bones and teeth.
It is widely used in construction (cement) and as a dietary supplement.

Strontium (Sr)

Strontium is a soft, silvery metal that burns with a bright red flame.
It is used in fireworks and in the production of magnets and certain glasses.

Barium (Ba)

Barium is a dense, silvery-white metal.
Primarily utilized in drilling fluids and as a contrast agent in medical imaging (barium swallow).

Radium (Ra)

Radium is a radioactive element.
Historically, it was used in cancer treatment and luminescent paints but is now largely avoided due to its health hazards.
