Document Summary
The periodic table of the elements is in the appendix 2 on page a-2 of the text (back of the text prior to the glossary) on a sheet handout along with this study guide. The periodic table shows the 92 naturally occurring elements on earth. It is important to understand the basics of this table. For example carbon (the symbol for carbon is c), which is one of the most important elements in biology, has the atomic number 6. On page 20 the author explains the structure of an atom. __nitrogen: as indicated in question 1, the atomic number of an element is determined by and is equal to the number of protons. One atom of any element has an equal number of protons and electrons. Thus the atomic number can be used to determine the number of electrons in an atom. There is a set structure for how these electrons are arranged.
