Elements and Compounds
The building blocks of matter
Elements
The smallest particle of an element
atom
The negatively charged part of an atom
electron

compound
The part of an atom with no charge
Neutron
The combination of substances where the materials can easily be
separated.
A mixture
This is a combination where one substance dissolves in another substance and cannot be easily
separated.
A solution
What is the name of the substance that will dissolve in a solution? (ex.
chocolate powder)
The Solute
What is the substance the solute will dissolve into? (ex. the milk)
The solvent
When the solvent has taken all the solute it can, we say it has
become______? (ex. no more chocolate can be added to the milk)
