Chapter 12
What is a bond and bond energy?
- * A Bond is a force that holds groups of two or more atoms together and makes them functional as a unit
- * Bond Energy is the energy required to break a bond

What types of bonds are there?
* Ionic bonds- The attraction between a strongly positive ion and a strongly negative ion
* Covalent bond- A bond is form between atoms with electrons are shared by the nuclei
What is electronegativity?
* The relative ability of an atom in a molecules to attract shared electron to itself
What is bond polarity and dipole moment?
* Polarity between bonds depends on the difference between the electronegativity values of the atoms forming the bond
* Dipole moment- The magnitudes of separated charges times the distance between the charges
Electron Configuration of Ions
1. Representative metals forms ions by losing enough electrons to achieve the configuration of the previous noble gas.
2. Nonmetals forms ions by gaining enough electron to achieve the configuration of the next noble gas
