Study Notes
Groups and Families
- Group 1: Alkali metals, characterized by their high reactivity and presence in nature only as compounds.
- Group 2: Alkaline Earth metals, slightly less reactive than alkali metals and known for forming basic oxides.
- Groups 3-12: Transition metals, known for their ability to form variable oxidation states and colored compounds.
- Group 13: Contains aluminum, important for its lightweight properties and used extensively in construction and packaging.
- Group 14: Includes carbon, crucial for organic chemistry and the foundation of life; known for forming diverse compounds.
- Group 15: Comprises nitrogen, essential for amino acids and DNA; constitutes most of Earth's atmosphere.
- Group 16: Oxygen, vital for respiration in living organisms; abundant in the Earth's crust and atmosphere.
- Group 17: Halogens, highly reactive nonmetals, often found in compounds; include fluorine and chlorine.
- Group 18: Noble gases, inert and stable gases at room temperature; typically do not react with other elements.
Element Classification
- Major classifications: Metals, known for their conductivity and malleability; Non-metals, characterized by their lack of metallic properties.
Terminology
- Two names for columns: Family and group are used interchangeably within the periodic table, denoting vertical arrangements of elements.
- Two names for rows: Periods and series indicate horizontal arrangements, reflecting increasing atomic number.
Special Categories
- Elements such as Boron, Silicon, Germanium, Arsenic, Antimony, and Tellurium are classified as semi-conductors or metalloids, exhibiting properties of both metals and non-metals.
- Mercury and bromine are unique as the two elements that naturally occur in a liquid state at room temperature.
Reactivity and Element Count
- Francium and fluorine are recognized as the two most reactive elements on the periodic table.
- Total number of elements confirmed in the periodic table is 115, with 18 defined groups and 7 periods, indicating the organization of elements based on similar properties.
