5 Matching questions

  1. What are ionic bonds?
  2. Do Hydrogen Bonds only occur with water molecules?
  3. What is a molecule?
  4. Define the potential energy level of electrons and the Kinetic energy level.
  5. How many electrons does it take to fill the first orbital shell? The second? The third?
  1. a No! Example: NH₃ (ammonia) is a hydrogen bond, the partial negative of Nitrogen bonds with the partial positive of Hydrogen.
  2. b Electron gaining or losing; e⁻ TRANSFER (NOT SHARING) between two atoms
  3. c Potential energy - stored energy due to location or structure; ready to use energy
    Kinetic energy - energy in motion or movement; currently using
  4. d First shell - 2
    Second shell - 8
    Third shell - 8
  5. e 2 or more atoms held together by covalent bonds

5 Multiple choice questions

  1. Elements required by organisms in minute quantities; ex: humans need iodine in small quantities or we'll get goiter
  2. CHNOPS: Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus, Sulfur
  3. a substance consisting of two or more different elements combined in a fixed ratio.
  4. Compound is a mixture of at least two different elements, while a molecule is a 2 or more atoms of a single element.
  5. Different forms of the same element; they differ in number of neutrons, but they have the same # of protons and behave identically in chemical reactions

5 True/False questions

  1. What is matter?Anything that takes up space and has mass. Ex: Air; something that isn't matter: light (think of the filling up a balloon metaphor)

          

  2. What are valence electrons?The electrons on the outermost orbital shell

          

  3. Are Van der Waals interactions weak or strong?The electrons on the outermost orbital shell

          

  4. What is an ion?Anything that takes up space and has mass. Ex: Air; something that isn't matter: light (think of the filling up a balloon metaphor)

          

  5. What are covalent bonds? Single? Double?The electrons on the outermost orbital shell
