Compound

A pure substance made from two or more elements.

 

 

Molecule
Groups of two or more atoms
Electron
A particle found floating in a cloud arround the nucleus of an atom.  It is impossible to know where an electron is at a given time.  This particle has a NEGETIVE charge
Proton
A particle found withing the nucleus of an atom.  This particle is completely surrounded by a cloud of electrons and has a POSITIVE charge.
Neutron
A particle that is also found in the nucleus of an atom.  This molocule is compleetly surrounded by a cloud of electrons and has a NEUTRAL charge.
Nucleus
The small matter in the center of the atom.  It is compleetly surrounded by a cloud of electrons and is made up of PROTONS and NEUTRONS
Mixture

An un-mixed collection of two or more substances that can be seperated WITHOUT requireing a chemical reaction.

 

EX:  SOIL

Solution

A solution is a heterogeneous mixture that is so finely mixed that you CAN-NOT see the diferent parts.


EX:  SALT WATER

Colloid

A solution that contains molocules that are of diferent states of matter at the SAME time.

 

EX:  BUTTER

Suspension

A combonation of molocules that are of a diferent state of matter at the SAME time, but they are NOT contained in the form of a solution.

 

EX:  FOG

Emulsion

A combonation of two liquids that do NOT mix together.

 

EX:  OIL AND WATER
