The flashcards below were created by user dante01 on FreezingBlue Flashcards. What would you like to do?


  1. Metals tend to _______electrons
    lose electrons to form cations
  2. Nonmetals tend to _______electrons
    gain electrons to form anions
  3. Atomic radius general trend
    • 1)increases down a groupĀ 
    • -electrons are farther from the nucleus, so size increases
    • 2)decreases left to right across a period
    • -increased nuclear charge creates greater interaction with electrons, so size decreases
  4. Ionization energy trend
    • 1)decreases down a group
    • -electron is farther from the nucleus, less interaction, easy to remove
    • 2)increases left to right
    • -increase in nuclear charge creates greater interaction, making it difficult to remove outer electrons
  5. Chemical bond
    a force that holds atoms together in a molecule or compound
  6. Two types of chemical bonds
    Ionic bonds and covalent bonds
  7. General properties of Ionic substances
    • -Crystalline solids
    • -very high melting/boiling point
    • -good electrical conductor
  8. General properties of Covalent substances
    • -Gases,liquids, or solids
    • -low melting/boiling point
    • -poor conductor of electricity
