5 Matching questions

  1. Define the potential energy level of electrons and the Kinetic energy level.
  2. What is the atomic mass?
  3. What's a positive ion called? A negative ion?
  4. What are our 6 Essential Elements?
  5. What is a compound?
  1. a Positive ion = CATION
    Negative ion = ANION
  2. b Potential energy - stored energy due to location or structure; ready to use energy
    Kinetic energy - energy in motion or movement; currently using
  3. c a substance consisting of two or more different elements combined in a fixed ratio.
  4. d CHNOPS: Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus, Sulfur
  5. e The number of protons and neutrons in nucleus.

5 Multiple choice questions

  1. Atoms that lose or gain electrons to complete their outer shell
  2. Anything that takes up space and has mass. Ex: Air; something that isn't matter: light (think of the filling up a balloon metaphor)
  3. The sharing of electrons UNEQUALLY; atoms have differing electronegativities
  4. Atoms interacting with each other to share, take, or give electrons.
  5. Weak.

5 True/False questions

  1. Do Hydrogen Bonds only occur with water molecules?Compound is a mixture of at least two different elements, while a molecule is a 2 or more atoms of a single element.

          

  2. Difference between compound and molecule?Covalent bonds are the SHARING of electrons, whether it be equally or unequally
    Ionic bonds are the GAINING or LOSING of electrons, NOT SHARING

          

  3. Define Subatomic particles, their charges, where they're found, and their relative mass.Potential energy - stored energy due to location or structure; ready to use energy
    Kinetic energy - energy in motion or movement; currently using

          

  4. What are non-polar covalent bonds?The sharing of electrons EQUALLY; atoms have similar electronegativities

          

  5. What are valence electrons?Elements required by organisms in minute quantities; ex: humans need iodine in small quantities or we'll get goiter
