5 Matching questions

  1. What are non-polar covalent bonds?
  2. What is a chemical reaction? Be able to identify the products and reactants in a chemical reaction.
  3. What is electronegativity?
  4. Define Subatomic particles, their charges, where they're found, and their relative mass.
  5. What are valence electrons?
  1. a The electrons on the outermost orbital shell
  2. b One atom's attraction of the electrons within one covalently bonded molecule
    O > N > C > H
    Oxygen - most electronegative element
  3. c The making and breaking of chemical bonds.
    1. Reactants - structure of chemicals prior to a chemical reaction
    2. Reaction
    3. Products - structure of chemicals as a result of a chemical reaction
  4. d The sharing of electrons EQUALLY; atoms have similar electronegativities
  5. e Protons - positive; in nucleus; 1 dalton (or amu)
    Neutrons - neutral; in nucleus; 1 dalton (or amu)
    Electrons - negative; found outside nucleus; 0 nothing

5 Multiple choice questions

  1. 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. Atoms that lose or gain electrons to complete their outer shell
  3. Ex: O - only 6 rings on outer shell, so it wants to gain 2, making it 2- charge
  4. Polar covalent bond.
    (it's when there's more than one polar molecule that hydrogen bonding takes place)
  5. Atoms interacting with each other to share, take, or give electrons.

5 True/False questions

  1. What are our 6 Essential Elements?CHNOPS: Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus, Sulfur


  2. What are the two strong chemical bonds?Atoms interacting with each other to share, take, or give electrons.


  3. What are isotopes?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


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


  5. What are ionic bonds?Electron gaining or losing; e⁻ TRANSFER (NOT SHARING) between two atoms
