Chemistry Form 4: Chapter 4 - Periodic Table

  • Elements in the periodic table are arranged in periods (row) and groups (column).
  • Groups include having the same electron arrangement in their outermost shell, which results in group elements sharing similar chemical properties.
  • The electrons in the outermost shell is termed valence electrons.
  • Valence electrons determine the chemical properties of the element and participate in chemical bonding.
