Chlorine is in period three because that is how many outer shells it has. One period is one shell... In the First outer shell you can only hold.. 2 electrons.
Second outer shell can hold 10 electrons. Third outer shell can hold 18 electron.
Protons + Electrons = Atomic Number
Atomic Number - Atomic Mass = Number of Neutrons in Outer Shells
