Question Answer
ProtonsAtomic number
Table NHalf life (add up the numbers)
Radioactive isotopesCan cause cancer
Radioactive isotopesAre used in medicine and to treat diseases
Going from a higher energy state to a lower energy stateBright light spectrum
Dalton's ModelElements are formed of atoms
Dalton's ModelAtoms of an element are the same
Rutherford ExperimentGold foil experiment
Rutherford ExperimentShowed atoms were mostly empty space with a small, dense positively charged nucleus
Bohr ModelDot diagrams (small, dense, positively charged nucleus surrounded by electrons in circular orbits)
Wave-Mechanical ModelElectron clouds
Wave-Mechanical ModelModern theory
Wave-Mechanical ModelOrbitals (most probable location of electrons)
Breaking a chemical bondEndothermic
Forming a chemical bondExothermic
MTV (melting to vaporization)FCC (freezing to condensation)
CovalentIonic and molecular compounds; sharing of electrons (CO)
Non-polarSymmetrical (perfect; unlike everyone)
Table OThe top number is the mass
Beta particleElectron
CompoundChemically combined
IsomerSame molecular formula, different structures
IsomerYou cannot touch them all with your pen
Subatomic particlesprotons (+), neutrons (0), electrons (-)
IsotopeSame amount of protons, different number of neutrons
HomogeneousMixture; looks the same
MetalsGood conductors of heat and electricity with mobile electrons; malleable
Valance electronsMost energy
Break a bondEnergy is absorbed/relieved
Atomic massNumber of neutrons plus protons
Hydrogen bondingFON (fluorine, oxygen, nitrogen)
HydrocarbonsHydrogen and carbon
OrganicNeeds carbon
RedoxReduction oxidation
OILRIGOxidation is losing electrons, reduction is gaining electrons
Charge of an atom0
ElectrolytesABS (acids, bases, salts)
AcidsH+ (Table K)
BasesOH (Table L)
SaltsIonic; metal and non-metal
AlcoholCOH (avoid)
One acid base theoryH+ (Acids donate, bases accept -- Acids have AD, Bases start with BA)
Greatest to weakestGBA (gamma ray, beta particle, alpha particle)
Weakest to greatestABG (alpha particle, beta particle, gamma ray)
FissionSplitting an atom
An OxAnode oxidation
Red CatReduction cathode
ProtonsCharge of the nucleus
TitrationNeutralize (with numbers)
More stuffMore molarity, more things to collide, less time
Molecular polarityPolar or non-polar
EquilibriumConcentration is constant, the rates of equal
Conversation of atomsHas to be same on both sides
Equilibrium, conversation of atomsHas to be the same on both sides
DistillationSeparation of liquids by boiling point
Losing an electron shellSmaller radius
Conserved in every chemical reactionMass, charge, energy (e=mc)
Salt bridgeMigration of ions
Table JHigher the element, the more oxidized it is (anode!)
Ideal gasesIdeal girls (HoT LiPs, high temperature, low pressure)
SolidsRegular geometric pattern
Naturally occurring isotopesWeighted average of atomic masses
NuclearGreatest amount of energy released
Highest electronegativityFlorine
Kinetic energyTemperature
Liquid that is a non-metalBromine
Liquid that is a metalMercury
Most polar bondBiggest difference in electronegativity
ElectrolyticElectrical energy is converted to chemical energy
VoltaicElectrochemical, chemical energy is converted to electrical energy
CathodeCoated (spoon, stick, fork, key, etc.)
More salt in waterThe boiling point elevates
EndothermicMore energy in Potential Energy Diagrams
ExothermicLess energy in Potential Energy Diagrams; released energy on the product side
Table HVapor pressure
CatalystLowers the activation energy
NeutralizationYou get salt and water
Heat flowHot to cold
