What role does lattice energy play in forming an ionic compound?

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.

Examples of Compounds Representing Ionic, Covalent, and Metallic Bonding

Ionic Bonding:
MgO
Magnesium Oxide

FeS
Iron (II) Sulfide

LiH
Lithium Hydride


Covalent Bonding:
NF₃
Nitrogen Trifluoride


N₂O₄
Dinitrogen Tetroxide


OF₂
Oxygen Diflouride

Metallic Bonding:
CuZn
Copper Zinc

Ti₆O
Titanium Oxide.


You can tell the difference between Ionic, Covalent and Metallic bonding easily. Ionic bonding will always have the second element ending in -ide. With Covalent bonding, there will always be a prefix in either one or both of the elements (example: mono-one. di- two. etc). With Metallic Bonding, there will always be a number of different elements.

Explain the forces that hold the bonds together

The Chemical bond is attracted and happens between molecules and atoms that have two or more atoms. Electromagnetic forces between different charges occurs between electrons and the nuclei. Metallic bonding happens between two electrons called delocalized, and conduction. Metallic bonding can be compared to some salts. Metallic bonding is the physical properties like the conductive of thermal and electric,luster and strength. With ionic bonds one element has a negative charge and the other has a positive. This is called an electrostatic attraction because its both a positive and negative charge.

Three Types of Bonding: Ionic, Covalent and Metallic

Ionic Bonding:
Ionic Bonding is a chemical bond that combines a metal and nonmetal ion. The bond happens between a negatively charged ion and a positively charged ion. In an ionic bond, the metal gives at least one of its electrons to the nonmetal which makes a cation. Once the electron is transferred over to the nonmetal, an anion (negatively charged electron) is formed. When an electron is removed, more energy is created. When metals and nonmetals attract, less energy is created. When bonded atoms have more energy than the free atoms, it's called being favorable. Ionic bonding will only happen when the atoms are favorable.

Covalent Bonding:
Covalent bonding is a chemical bond that combines metals with other metals. In covalent bonding, the bonding doesn't necessarily have to happen between the same elements as long as they have comparable electronegativities.  In order for a Lewis Structure with a covalent bond to be complete, there must be a full octet. A full octet mean that each element has eight electrons. When drawing a Lewis Structure, there are many things to consider. There are double bonds which is four electrons connecting an element as well as triple bonds which has six electrons connecting an element. Another thing to consider is that Hydrogen (H) has a full octet with two electrons. There can also be more than four elements connected to the central one.

Metallic Bonding:
Metallic Bonding occurs bewteen delocalised electrons and the metal nuclei. These bonds happen between solid metals and liquid metals. When metals reach their boiling point and melt, they combine. The delocalised move in a solid lattice. Mobile electrons act as charge carriers or energy carriers.
