Matter
Anything with mass and volume
Atom
Smallest particle of an element that still has the same chemical properties (neutral charge)
Ion
Atom or group of atoms that gained or lost electrons to form charge
Molecule
Neutral group of atoms connected by covalent bonds
Configuration
Mixture is spun at high speeds creating a force that pulls heavier particles near the bottom
Chromatography
Mixture is applied to a solid support and separated into its components by solvent.
(Carries components to different rates)
Rf value
Height of colour divided by height of water
Crystallization
Mixture is concentrated and cooled until solid component slowly forms
Distillation
Mixture is heated until liquid component reaches boiling point and evaporated
Electrolysis
Electric current is applied to sample, decomposing sample into its component elements
Filteration
Solid component of mixture becomes trapped in a screen,allowing liquid to go through
Floatation
Chemicals (oil/detergent) added to mixture, air is forced through mixture to stir
Settling
Components of a mixture separate into layers of their own
