- 1The three subatomic particles with chargeselectrons(-1), protons(+1), and neutrons(0)
- 2What defines the atomic numberThe number of protons

- 4What is oxidationLoss of electrons
- 5What is reductionGain of electrons
- 6What element makes a compound organicCarbon
- 7What is a nonpolar covalent bondA bond where electrons are shared equally
- 8What is a polar covalent bondA bond where electrons are not equally shared due to varying electronegativity
- 9What are hydrogen bondsBonds that form between a negative oxygen and a positive hydrogen
- 10CoheisveWater molecules are attracted to each other
- 11AdhesiveThe attraction of water and another polar molecule NOT WATER
- 12Specific HeatA large amount of thermal energy is needed to break the hydrogen bonds.
- 13Heat of VapotizationAmount of energy needed to change 1 gram of a substance from a liquid to a gas
- 14Hydration shellPrevents molecules from associating with other molecules
- 15HydrophobicShy away from contact with water

- 17Hydrophobic ExclusionNonpolar molecules aggregate with water
- 18pH ScaleUsed to scale the hydrogen ion concentration
- 19pHPartial hydrogen
- 20AcidsDissociates in water to increase concentration of hydrogen ions
- 21BasesDissolve in water, lowering the concentration of hydrogen ions
- 22BuffersResists changes to pH
