Study Notes
Periodic Table Overview
- The periodic table displays all known chemical elements, organized based on their properties.
Rows and Columns
- The horizontal rows are called Periods.
- The vertical columns are referred to as Groups or Families.
Element Properties
- Elements within the same group or family share similar reactivity and properties.
Alkali Metals (Group 1)
- Soft, silvery metals that are highly reactive, especially with water, leading to alkaline solutions.
Alkaline Earth Metals (Group 2)
- Shiny, silvery-white metals that possess moderate reactivity.
Nitrogen Family (Group 15)
- Mostly solid at room temperature (with nitrogen as an exception), conductivity increases down the group and they form stable bonds.
Boron Family (Group 13)
- Comprises soft metals with low melting points and exhibits good electrical conductivity, excluding Boron.
Carbon Family (Group 14)
- Shows increasing metallic properties down the group, generally has lower melting and boiling points.
Transition Metals (Groups 3-12)
- Known for their shiny appearance and diverse bonding capabilities with other elements.
Oxygen Family (Group 16)
- Typically soft materials with poor conductivity; metallic characteristics increase down the group alongside melting and boiling points.
Halogens (Group 17)
- Composed of poisonous, colored gases that exist as diatomic molecules and are common in cleaning agents (e.g., bleach).
Noble Gases (Group 18)
- Colorless, monatomic, and unreactive gases; their chemical inactivity makes them suitable for use in light bulbs.
Lanthanides
- Rare earth metals located in the second to last row of the periodic table, naturally occurring elements.
Actinides
- Rare earth metals found in the last row of the periodic table, which are not typically found in nature and are all radioactive.
