Chemical Bonds

Chemical Bonds. Chapter 8. A Chemical Bond is a link between atoms. An Ionic Bond is the electrical attraction between the opposite charges of cations and anions. A Lewis symbol consists of the chemical symbol of an element and a dot for each of its valence electrons.Example He:

CI 4.5

CI 4.5. Energy changes in solutions. Why do some ionic substances dissolve in water, whilst others are insoluble?. If there is enough energy to separate the ions in the lattice, the substance will be soluble. Ions in solid lattice. Ions in solution. - ?H LE is a positive value.
