Some basic chemistry required for BIO 311C (Some questions are adapted from Dr. Weiss’s chemistry homework) Use the periodic table to answer some of the questions:    31 1.  Using    P as an example,    15 (a) What is the NAME given to the top number, the 31? (b) What atomic particles are represented by the 31? (c) What is the NAME given to the bottom number, the 15? (d) What atomic particles are represented by the 15? (e) How many electrons are present in each atom of this element? 2. What does the reactivity of an atom depend on? 3. Based on electron configuration, which of these elements would exhibit chemical behavior  most like that of oxygen? (Carbon, nitrogen, sulfur, hydrogen, phosphorous)? 4. How many electrons can be expected in the outermost shell of an atom with atomic number  12? 5. What is the maximum number of electrons in the 2p orbital of an atom? 6.  Some elements are referred to as being “inert.” Why is this? Are they commonly found as part  of a chemical compound? 7.  The half-life of the radioisotope  32 P is 14.3 days. How many days will it take for 1 gram of  32 P to decay to 0.25 grams? 8.
