Atoms
Anything that has mass and takes up space.
Matter
Ability of an atom to attract electrons in a bond.
Electronegativity
Attractions between molecules.
Intermolecular Forces
Measure of Acidity
pH
Substance that lowers activation energy
Catalyst
Positively charged particle in the nucleus. Has a mass of 1 amu
What is a Proton
Atoms gain, lose, or share electrons to obtain 8 valence electrons.
Octet Rule
Strong attraction involving H bonded to N, O, or F.
Hydrogen Bonding
Produces OH- in water.
Arrhenius Base
Predicts equilibrium shifts after a stress.
Le Châtelier’s Principle
Number of protons in an atom.
What is Atomic Number
Attraction between oppositely charged ions.
Ionic Bond
Compounds that are only conductive when liquid or dissolved in water
Ionic Compounds
Donates H+
Bronsted Lowry Acid
Loss of electrons
Oxidation
Positively charged ion.
What is a Cation
Attraction between metal cations and delocalized electrons.
Metallic Bond
Solids that are made of only nonmetals and have very high boiling points
network Covalent solids
The only difference between these two is one has one more H+
Conjugate Acid/Base pair
Produces electricity from a spontaneous redox reaction
Voltaic/Galvanic Cell
Atoms of the same element with different numbers of neutrons.
What is an Isotope
Unequal sharing of electrons.
Polar Covalent Bond
Why coal is a solid but methane is a gas
Higher London Dispersion Forces/ Larger Molecular Weight
Method used to determine concentration
Titration
Splitting a large nucleus
Fission
