2.
3.
4.
Proton
Neutron
Electron
Nucleus
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 the
“building blocks” of all matter?
Many periodic tables look different but still contain similar information.
1. Atomic Number



Number of Protons
Number of Electrons
Number of Protons = Number of Electrons
2. 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).
