• Covalent bonding


  Bonding that occurs when non-metal atoms share electrons
• Covalent bond


  • Strong bond formed by shared pair of electrons
• Covalent bonding

  Shared pair of electrons between non-metal atoms
• Covalent bond

  • Energy level diagram
  • Dot and cross diagram
  • Stick diagram
• Covalent bonding

  Sharing of electrons between atoms
• Covalent bonding allows atoms to achieve full outer energy level
• Dot and cross diagrams can be used to show covalent bonding
