Transcript

  • 1. ChemicalBonding
  • 2. Chemical bonding is… when two or more elements combine together to form a new substance a connection between atoms
  • 3. Two Types1. Ionic Bonding2. Covalent Bonding Other examples could be hydrogen or metallic bonding.
  • 4. Ionic Bonds  Does NOT share!  Transfer electrons  Cation: Donates electron  Anion: Receives electron  Groups 1,2,3 with 15,16, and 17
  • 5. Covalent Bonds Shareelectrons Non-metal + Non-metal Bonding with groups 14, 15, 16, and 17
  • 6. Covalent Bonding vs. Ionic Bonding
  • 7. NamingIonic Bonds ________ + ______-ide 1st element + 2nd element-ide Ex: Ca+S=Calcium SulfideCovalent Bonds prefix-______+ prefix-_____-ide Prefix-1st element + prefix-2nd element Ex: P4S5= Tetraphosphorus Pentasulfide Numerical prefixes for covalent bonding:
