Science Joke....
Do you know why we can't trust Atoms? ...
The ATOM
Blank Side | Lined Side |
|---|---|
The Atom | Dense Center (protons, Neutrons) and Electrons orbit around it. |

REMEMBER and write in Index Cards
Counting Mass and Neutrons
Blank Side | Lined Side |
|---|---|
M-A=N | Mass- Atomic Number(protons)= Neutrons |
A=P=E | Atomic #=Protons=Electrons |

The charge is not the same as mass. Charge is about the electrical charge it contains.
Electrons- Negative
Neutrons - none
Protons -Positive
Count them like soldiers of diff teams.
