  1. Different Element Families Allie Ruiz

  2. Metals • High melting points • Many of the properties of metals, including large atomic radius, low ionization energy, and low electro negativity, are due to the fact that the electrons in the valence shell of a metal atoms can be removed easily • Ability to be deformed without breaking • For example Includes: steel, aluminum,

  3. Non-Metals • very brittle • exist in two of the three states of matter at room temperature: gases (such as oxygen) and solids (such as carbon) • Include : Hydrogen, Carbon, Nitrogen, Oxygen, Phosphorus, Sulfur, Selenium

  4. Metalloids • Metalloids have properties of both metals and non-metals • Some of the metalloids are semi-conductors, This means that they can carry an electrical charge under special conditions • Include: Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, Polonium

  5. Alkali Metals • very reactive metals that do not occur freely in nature • have only one electron in their outer shell • softer than most other metals • can explode if they are exposed to water • Include: Lithium, Sodium, Potassium, Rubidium, Cesium, Francium

  6. Alkaline Earth Metals • have an oxidation number of +2, making them very reactive • not found free in nature because of reactivity • Include: Beryllium, Magnesium, Calcium, Strontium, Barium, Radium

  7. Transition Metals • their valence electrons, or the electrons they use to combine with other elements, are present in more than one shell • often exhibit several common oxidation state • Include: Scandium, Titanium, Vanadium, Chromium, Manganese, Iron, Cobalt, Nickel, Copper, Zinc, Yttrium, Zirconium, Niobium, Molybdenum, Technetium, Ruthenium, Rhodium, Palladium, Silver, Cadmium, Hafnium. Tantalum, Tungsten, Rhenium, Osmium, Iridium, Platinum, Gold, Mercury, Rutherfordium, Dubnium, Seaborgium, Bohrium, Hassium, Meitnerium, Ununnilium, Unununium, Ununbium

  8. Halogen • The term "halogen" means "salt-former" and compounds containing halogens are called "salts” • All halogens have 7 electrons in their outer shells, giving them an oxidation number of -1 • Exists in all three states of matter at room temperature • Include: Fluorine, Chlorine, Bromine, Iodine, Astatine

  9. Noble Gases • their oxidation number of 0 prevents the noble gases from forming compounds readily • have the maximum number of electrons possible in their outer shell (2 for Helium, 8 for all others), making them stable • Include: Helium, Neon, Argon, Krypton, Xenon, Radon
