It tells you what element it is. • Chemical Symbol – Shorthand way of writing element • Atomic Number – Protons in Nucleus • Atomic Mass – Protons + Neutrons in Nucleus Arrangement of the Periodic Table Groups or Families • Vertical columns Periods • Horizontal columns • Elements have similar chemical properties • Atomic number increases from left to right. • What gives atoms/elements their chemical properties? • The Period an element is in determines the number of “race tracks” for the electrons of the atom.
