How Many Periods are in the Periodic Table

  • Each horizontal row of elements in the Periodic Table is known as a period.
  • The Periodic Table consists of seven periods, from Period 1 to Period 7.
  • When going across Period 2 and Period 3 from left to right
    • the proton number increases by one from one element to the next
    • the number of valence electrons increases by one from one element to the next.
