1

Matter

Anything with mass and volume

2

Atom

Smallest particle of an element that still has the same chemical properties (neutral charge)

3

Ion

Atom or group of atoms that gained or lost electrons to form charge

4

Molecule

Neutral group of atoms connected by covalent bonds

5

Configuration

Mixture is spun at high speeds creating a force that pulls heavier particles near the bottom

6

Chromatography

Mixture is applied to a solid support and separated into its components by solvent.
(Carries components to different rates)

7

Rf value

Height of colour divided by height of water

8

Crystallization

Mixture is concentrated and cooled until solid component slowly forms

9

Distillation

Mixture is heated until liquid component reaches boiling point and evaporated

10

Electrolysis

Electric current is applied to sample, decomposing sample into its component elements

11

Filteration

Solid component of mixture becomes trapped in a screen,allowing liquid to go through

12

Floatation

Chemicals (oil/detergent) added to mixture, air is forced through mixture to stir

13

Settling

Components of a mixture separate into layers of their own
