Elements classified as Metalloids
The 7 elements classified as "Metalloids" are located in Groups 13, 14, 15, 16 and 17 elements of the Periodic Table. Elements classified as Metalloids have properties of both metals and non-metals. Some are semi-conductors and can carry an electrical charge making them useful in calculators and computers
The Metalloids are:

  • Boron
  • Silicon
  • Germanium
  • Arsenic
  • Antimony
  • Tellurium
  • Polonium

Elements classified as Alkali Metals
The 6 elements classified as "Alkali Metals" are located in Group 1 elements of the Periodic Table. Elements classified as Alkali Metals are very reactive metals that do not occur freely in nature. Alkali metals are soft, malleable, ductile, and are good conductors of heat and electricity. The Alkali Metals are:

  • Lithium
  • Sodium
  • Potassium
  • Rubidium
  • Cesium
  • Francium

Elements classified as Alkaline Earth Metals
The 6 elements classified as "Alkaline Earth Metals" are located in Group 2 elements of the Periodic Table. Elements classified as Alkaline Earth Metals are all found in the Earth’s crust, but not in the elemental form as they are so reactive. Instead, they are widely distributed in rock structures. The Alkaline Earth Metals are:

  • Beryllium
  • Magnesium
  • Calcium
  • Strontium
  • Barium
  • Radium

Elements classified as Transition Metals
The elements classified as "Transition Metals" are located in Groups 3 - 12 of the Periodic Table. Elements classified as Transition Metals are ductile, malleable, and conduct electricity and heat. The Transition Metals are:

  • Scandium
  • Titanium
  • Vanadium
  • Chromium
  • Manganese
  • Iron
  • Cobalt
  • Nickel
  • Copper
  • Zinc
  • Yttrium
  • Zirconium
  • Platinum
  • Gold
  • Mercury
  • Rutherfordium
  • Dubnium
  • Seaborgium
  • Bohrium
  • Hassium
  • Meitnerium
  • Ununbium
  • Niobium
  • Iridium
  • Darmstadtium 
  • Molybdenum
  • Technetium
  • Ruthenium
  • Rhodium
  • Palladium
  • Silver
  • Cadmium
  • Hafnium
  • Tantalum
  • Tungsten
  • Rhenium
  • Osmium

Elements classified as Other Metals
The 7 elements classified as "other metals" are located in groups 13, 14, and 15 elements of the Periodic Table. All of these elements are solid, have a relatively high density and are opaque.
The "Other Metals" are:

  • Aluminium
  • Gallium
  • Indium
  • Tin
  • Thallium
  • Lead
  • Bismuth

Elements classified as non-metals
The 7 elements classified as "non-metals" are located in Groups 14,15 and 16 of the Periodic Table. non-metals are not easily able to conduct electricity or heat and do not reflect light . Non-metallic elements are very brittle, and cannot be rolled into wires or pounded into sheets. Non-metallic elements exist, at room temperature, in two of the three states of matter : gases (such as oxygen) and solids (such as carbon).
The Non-Metal elements are:

  • Hydrogen
  • Carbon
  • Nitrogen
  • Oxygen
  • Phosphorus
  • Sulfur
  • Selenium

Elements classified as Halogens
The 5 elements classified as "Halogens" are located in Group 7 elements of the Periodic Table. The term "halogen" means "salt-former" and compounds containing halogens are called "salts". The halogens exist, at room temperature, in all three states of matter - Gases such as Fluorine & Chlorine, Solids such as Iodine and Astatine and Liquid as in Bromine. The Halogen elements are:

  • Fluorine
  • Chlorine
  • Bromine
  • Iodine
  • Astatine

Elements classified as Noble Gases
The 6 elements classified as "Noble Gases" are located in Group 18 elements of the Periodic Table. The elements forming the Six Noble Gases are:

  • Helium
  • Neon
  • Argon
  • Krypton
  • Xenon
  • Radon

Elements classified as Rare Earth Elements
The elements classified as "Rare Earth Elements" are located in Group 3 elements of the Periodic Table and in the 6th and 7th periods. The Rare Earth Elements are of the Lanthanide and Actinide series. Most of the elements in the Actinide series are synthetic or man-made.
