All Sections: Using Chapter 5 of your textbook, complete the following:

1) Define
       a) atomic radius
       b) electronegativity
       c) ion(s)
       d) ionization energy
       e) electron affinity

2) Describe the periodic trend for each of the following (the first one is done for you as a guide)
       a) atomic radius - decreases from left to right across a row and increases down a group
       b) electronegativity
       d) ionization energy

3) Use the concept of ionization energy to explain why sodium form a 1+ ion (Na+) but
magnesium forms a 2+ ion (Mg2+).

4) What is the difference between electron affinity and ionization energy?
