Bonding and structure

• octahedral = 6 bonded, 0 lone pairs, 90 degrees
• the difference in structure and bonding between a ionic and covalent bond.

  ionic bonds are stronger and has a giant ionic lattice and covalent bonds are weaker and have weaker London forces.
• why is a compound unreactive

  it has no lone pair of electrons or non-polar
• ionic bonding

  the electrostatic attraction between oppositely attracted ions
