Checking for understanding

5. What information does the periodic table provide?
Many periodic tables look different but still contain similar information.

6. A square on the periodic table
1. Atomic Number
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).
