“building blocks” of all matter?

5. Many periodic tables look different but still contain similar information.

6. 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).
