Unit 6

1. ATOMIC BONDING

   • Ionic Bonding : Transfered electrons. Happens between metals and none-metals
   • Metalic Bonding: Collectively shared electrons. Happens between metals

2. ATOMIC BONDING

   • Metalic Bonding: Collectively shared electrons and it happens with metals
   • Ionic Crystals: This is created by the atraction of different charges of the atoms.(The geometric shape depends on the nature of the bonding)
   • What is a mole? A mole of a substance is the amount that contains the same number of units. This units can be atoms,molecules or ions.
   • Avogrado Constant: Thanks to the work of the italian scientist Avogrado, we know that 12g of Carbon-12 contains 6.022 × 10(elevado)23 carbon atoms!
   • Covalent Bonding: Shared electros and this happens when non-metals bond togather
   • Ionic Bonding: Transfered electrons and this happens between metals and none-metals
