The Nature of Molecules

Question	Answer
The three subatomic particles with charges	electrons(-1), protons(+1), and neutrons(0)
What defines the atomic number	The number of protons
How do you find the atomic mass	Adding the number of protons and neutrons
What is oxidation	Loss of electrons
What is reduction	Gain of electrons
What element makes a compound organic	Carbon
What is a nonpolar covalent bond	A bond where electrons are shared equally
What is a polar covalent bond	A bond where electrons are not equally shared due to varying electronegativity
What are hydrogen bonds	Bonds that form between a negative oxygen and a positive hydrogen
Coheisve	Water molecules are attracted to each other
Adhesive	The attraction of water and another polar molecule NOT WATER
Specific Heat	A large amount of thermal energy is needed to break the hydrogen bonds.
Heat of Vapotization	Amount of energy needed to change 1 gram of a substance from a liquid to a gas
Hydration shell	Prevents molecules from associating with other molecules
Hydrophobic	Shy away from contact with water
Hydrophilic	Polar molecules that easily bond with water
Hydrophobic Exclusion	Nonpolar molecules aggregate with water
pH Scale	Used to scale the hydrogen ion concentration
pH	Partial hydrogen
Acids	Dissociates in water to increase concentration of hydrogen ions
Bases	Dissolve in water, lowering the concentration of hydrogen ions
Buffers	Resists changes to pH
