Lattice energy plays a very important role in forming an ionic compound. Lattice energy is what gives electrons energy to move across and bond with other electrons to form a compound.

What are bond energies and how do they relate to stability of bonds?
A bond energy is the ammount of bond strength in a chemical compound. It's also the required heat to break Avogardo's number of molecules to be an individual number.
Stability of Bonds is simply the strength of a bond a compound has.
They relate because they both have to do with a chemical compound and their strength of bonding.

High Bond Energies of Salts are Used as an Argument by Some Scientists to Support Plans to Bury Toxic Waste in Salt Domes
Scientists believe salt domes would be a good place to store toxic wastes because they're stable enough to not let the waste come out and contaminate human resources. Also, salt isn't a very reactive compound so it would take a long time for toxic waste to react with salt.

Energy and Stability when an Atom Chemically Bonds.
An atom becomes more stable when it forms a chemical bond. Energy can't be determined unless we know if it will gain or lose electrons.
Octet Rule
The Octet Rule is quite simple. It basically means that in order for an element to be full, it has to have a full octet. A full octet consists of eight atoms in an element. Exceptions to the rule of eight are Hydrogen and Helium which only need two.Beryllium, Alluminum, and Lithium also do not follow the Octet Rule. The Octet Rule relates to the formation of a bond because it states how many electrons is needs to correctly bond to another element.
Explain Why Atoms of the Noble Gases do not Easily Form Bonds, Unlike Other Atoms.
Noble gases don't easily form bonds like other atoms because their outter most electron shell is filled. When other atoms react, it's because they try to fill their outter most shell, but because noble gases already have theirs filled, they don't need to react. It is possible for a noble gas to reach, though.

Compare and Contrast Ionic, Covalent and Metallic bonds.
Covalent bonds occur when one or more electrons are joined by two atoms. Ionic bonds occur when one or more of the electrons are attached to another atom, or are removed. When that happens it creates positive and negative ions that can join with each other. Metallic bonds happens between metals, they share unplaced electrons. In the valence shell of metal atoms they have a small amount of electrons.
