Study Notes
Alkaline Earth Metals (Group 2A)
- 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.
Individual Elements in Group 2A
- 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.
Boron Family (Group 3A)
- 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.
Individual Elements in Group 3A
- Boron (B): Used in glass and ceramics; crucial for plant growth.
