Atoms and molecules glossary

ATOMS
Tiny particles that make up all things.

CENTRIFUGING
Separation of a solid from a liquid by spinning them rapidly until the
solid is stuck to the bottom.

COMPOUND
Combinations of different types of atoms.

DECANTING
Separation of two immiscible liquids by waiting until they separate and
then pouring off the top layer.

DISSOLVE
To break into component parts when mixed with a (liquid or gas) solvent.


DISTILLATION
Separation of gases by gradually cooling them until one becomes a liquid
while the others remain gaseous.

ELECTRON
Small negatively charged particle within atoms.

ELEMENT
A substance made up of only one type of atom.

EMULSION
A mixture of immiscible liquids in which one forms small droplets
suspended in the other.

EVAPORATION
Converting a liquid to a gas by heating it.

FILTRATION
Separation of a solid from a liquid by passing it through a mesh or
filter paper.

IMMISCIBLE
Liquids or gases that cannot be mixed or spontaneously separate once
mixed.

INSOLUBLE
Unable to dissolve.

MISCIBLE
Liquids or gases that cannot be mixed and do not spontaneously separate
once mixed.

MOLECULE
Combinations of two or more atoms.

MIXTURE
Made out of more than one type of molecule.

NEUTRONS
A neutrally charged particle in the nucleus of atoms.

PAPER CHROMATOGRAPHY
Separating dissolved substances based on the rate at which they travel
through a piece of paper.

PRECIPITATION
When a dissolved substance becomes insoluble.

PROTONS
A positively charged particle in the nucleus of atoms.

PURE SUBSTANCE
Made out of only one type of molecule.

SOLUTE
Material which is dissolved in a solvent.

SOLUTION
A mixture of dissolvent solid particles and a (liquid or gas) solvent.

SOLVENT
A liquid or gas in which material is dissolved.

SUSPENSION
A mixture of insoluble solid particles in a liquid or gas.
