Periodic Table Group 2A and 3A Flashcards

Comprised of six elements: Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba), and Radium (Ra).
Group is characterized by the presence of two electrons in their outermost shell.
Elements are known for their reactivity, especially with water, and typically form alkaline solutions.

Beryllium (Be): Lightweight, strong metal used in aerospace materials.
Magnesium (Mg): Important for biological functions; used in alloys and firework production.
Calcium (Ca): Essential for living organisms; major component of bones and teeth.
Strontium (Sr): Employed in fireworks for red color and in medical imaging.
Barium (Ba): Used in medical diagnostics as a radiocontrast agent.
Radium (Ra): Radioactive element historically used in luminescent paint.

Consists of five elements: Boron (B), Aluminum (Al), Gallium (Ga), Indium (In), and Thallium (Tl).
Group is characterized by having three electrons in their outermost shell.
Elements exhibit a range of metallic and non-metallic properties.

Boron (B): Used in glass and ceramics; crucial for plant growth.
Aluminum (Al): Widely used metal, known for its light weight and corrosion resistance; common in packaging and construction.
Gallium (Ga): Notable for low melting point; used in electronics and LED technology.
Indium (In): Soft metal used in electronics, especially in touchscreens and LCDs.
Thallium (Tl): Toxic element used in some electronics and in specialized industrial applications.

Group 2A includes Be, Mg, Ca, Sr, Ba, Ra.
Group 3A includes B, Al, Ga, In, Tl.
Both groups play important roles in various industrial, chemical, and biological applications.
