AB
SaturatedThis is when a solvent can't dissolve any more solute
VacuumThis is the absence of matter
MassThe amount of matter in an object (measured in grams)
VolumeThe amount of space an object fills (cm cubed, or mL)
SoluteThe substance such as sugar that gets dissolved
SolutionA well-mixed mixture, often with one thing dissolved in another
DensityHow much matter is packed into an object
SolventA substance, such as water, that does the dissolving
ConcentrationThe amount of a substance in a solution (think kool aid)
NucleusThe center of an atom
CompoundTwo or more elements chemically combined
MixtureTwo or more substances that have been physically combined
ProtonPositive particle, found in nucleus
NeutronNeutrally charged particle, found in nucleus
ElectronNegatively charged particle, orbits nucleus
IonA charged atom, with too many or too few electorns
IsotopeAn atom with too many or too few neutrons
Ionic bondCombination of a non-metal with a metal, and electrons are given or taken. Two ions combine (one positive, one negative)
Covalent bondA non-metal combined with another non-metal, electrons are shared.
Atomic NumberThe number of protons in an atom
Atomic MassThe weight of an atom (number of protons plus neutrons) Weight in grams needed to have one mole of substance
MoleA number that represents the amount of substance you have. It is equal to 6.022 x 10^23
Graduated CylinderTube with markings used to measure a precise amount of liquid
Density greater than oneObject will sink in water
Density less than oneObject will float in water
