1. Protons: Positive charge
2. Neutron: Neutral
3. Electron: Negative Charge
4. Nucleus: Center of atom
Why is it appropriate to say that atoms are

Many periodic tables look different but still
contain similar information.

Number of Protons
Number of Electrons
Number of Protons = Number of Electrons
2. Chemical Symbol: Letter(s) that represent
the element (Always begins with a capital
letter).
3. Atomic Mass: Number of Protons + the
Number of Neutrons in one atom of the
element (an average).
