Graph 1 - Atomic Radius as a function of Atomic Number A. Create a graph of the atomic radius as a function of atomic number. Plot atomic number on the X axis and
atomic radius on the Y axis. Remember to label the axes!
B. Use a colored pen, pencil or highlighter to trace over the element's period (horizontal row on the periodic
table). For example: use GREEN to trace for all of the elements in row 1, then use YELLOW to trace for
all of the elements in row 2, then use ORANGE to trace for all the elements in row 3, then use BLUE to
trace for all the elements in row 4.

1. Describe the trend in atomic radius as the atomic number increases across a period.
2. Describe the trend in atomic radius as the atomic number increases down a group.
