•Protons- Positive•Neutrons- Neutral•Electron- Negative
Which 2 parts of the atom have
the most mass?
Protons and Neutrons
They make up most of the mass
of the atom
Where can Valence electrons
be found?
In the outer shell
Also known as a electron
cloud
In an atom or isotope, the number of
protons is equal to the number of
___?

Chemical Reaction
What is the Law of Conservation
of Mass (in a chemical reaction)?
In a chemical reactions, atoms
are neither created or destroyed,
merely rearranged
What does a catalyst do?
