Chemistry -- Families of the Periodic Table

>
Welcome to my Families of the Periodic Table website. Below, you will find the families, their properties, and other information. I'll also supply you with some websites that I recommend for further periodic table information. I hope this is benificial to you!

1. ALKALI METALS

  • Group IA
  • The most reactive of all the metals
  • All alkali metals have 1 electron in their outermost energy levels
  • They form positive ions

    2. ALKALI EARTH METALS
  • Group IIA
  • Less reactive than the alkali metals
  • Generally white in color
  • They have higher melting and boiling points

    3. TRANSITION METALS
  • Elements that have certain characteristics, but cannot fit into any other category
  • Known for hardness, high melting points, high boiling points, and heat conduction.

    4. METALLOIDS/SEMI-METALS
  • Possesses properties of both metals and non-metals
  • Silicon is a main metalloid

    5. HALOGENS
  • Group VIIA
  • Extremely reactive

    6. NOBLE GASES
  • Group VIIIA
  • Inert
  • Unreactive, but not non-reactive

    Legend
    Metals A solid substance that is a good conductor of heat and electricity. Can be formed into many shapes.
    Metalloid "Middle elements" - conduct heat and electricity better than nonmetals, but not as well as metals. Easier to shape than nonmetals, but not as easy as metals. Solid at room temperature.
    Nonmetals A poor conductor of heat and electricity. Not easily formed into shapes.
