Prepare a 350- to 700-word paper in which you describe the periodic nature and properties of atoms and molecules.

Compare properties of molecules formed from atoms in similar families; for example, H2S versus H2O.
Explain what is meant by the electronic structure of atoms. How does knowing the electronic structure of atoms aid chemists in predicting chemical reactions?
