Chemical Bonding

• Chemical Bond


  Mutual attraction between two atoms resulting from the simultaneous attraction between their nuclei and the outer electrons
• Ionic bond (transferred)


  Transfer of electrons from a metal to a non-metal
• Covalent bond (shared)


  electrons are transferred between non-metals to form a molecule
• Molecule


  A group of two or more atoms covalently bonded and that functions as a unit
• Valence Electrons


  The electrons in the highest energy level of an atom in which there are electrons
• Bonding pair 


  A pair of electrons that is shared between two atoms in a covalent bond
• Lone Pair


  A pair of electrons in the valence shell of an atom that’s not shared with another atom
