  1. What bond does a SINGLE molecule of water have? (H₂O)
  2. What is matter?
  3. What's a positive ion called? A negative ion?
  4. What is a hydrogen bond? Strong or weak?
  5. What are our 6 Essential Elements?
  1. a CHNOPS: Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus, Sulfur
  2. b Polar covalent bond.
    (it's when there's more than one polar molecule that hydrogen bonding takes place)
  3. c Anything that takes up space and has mass. Ex: Air; something that isn't matter: light (think of the filling up a balloon metaphor)
  4. d Partial plus of a Hydrogen in a polar molecule forms a bond with a Partial Minus of another polar molecule; Weak bond.
  5. e Positive ion = CATION
    Negative ion = ANION

5 Multiple Choice Questions

  1. Covalent bonds are the SHARING of electrons, whether it be equally or unequally
    Ionic bonds are the GAINING or LOSING of electrons, NOT SHARING
  2. Compound is a mixture of at least two different elements, while a molecule is a 2 or more atoms of a single element.
  3. a substance consisting of two or more different elements combined in a fixed ratio.
  4. Atoms interacting with each other to share, take, or give electrons.
  5. Covalent bonds (STRONGEST) and Ionic bonds.

5 True/False Questions

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

          

  2. 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

          

  3. Choose 2 elements essential to life, draw the electron configuration of each as an ion and note the charge of the ion.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 isotopes?Electron gaining or losing; e⁻ TRANSFER (NOT SHARING) between two atoms

          

  5. 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)
