Chemistry

1. Atom Structure + Periodic Table

   • From B - At, the "stairs" indicate Non-Metals on the left, Metals on the right.
   • Each letter represents a single Atom. "O" represents a singular Oxygen atom.
   • Atoms
     • Nucleus contains Protons and Neutrons. Nucleus is surrounded on the outside with Electrons. Each have Charges.
     • The Chlorine Atom here has 17 Protons, it will also have 17 Electrons because Electrons and Protons have the same amounts. The sum of Protons and Neutrons here is 35, you can work it out by doing 35-17=18 Neutrons.
