Answer» Answer: Chapter 1 "Introduction to Chemistry" through Chapter 5 "Energy Changes in CHEMICAL Reactions" introduced you to a wide variety of chemical substances and some of the most FUNDAMENTAL CONCEPTS in chemistry, including general descriptions of chemical bonding, mass relationships in chemical equations, and the energy changes associated with chemical reactions. You learned that the atoms of each element contain a unique number of positively charged protons in the nucleus and that a NEUTRAL atom has the same number of ELECTRONS as protons. You also learned that protons and neutrons constitute most of the mass of the atom and that electrons occupy most of the volume of an atom. These facts do not, however, explain the stoichiometries and the structures of chemical compounds; a deeper understanding of the electronic structure of atoms is required. |
