Trends in Graphs
I was given a list of the 20 first elements in the periodic table, each with the atomic number, Ionization energy, and the Atomic radius. I was to create two different graphs; Ionization energy vs. Atomic number and Atomic radius vs. Atomic number. Then, I had to interpret the graph and point out the trend or trends in both graphs. Below that I had to write a paragraph explaining the trends and define Ionization energy and atomic radius. (Attachment below)

Justification
I chose this project because it includes the skills above. Upon completion I have acquired knowledge about several things, such as knowing the definition of ionization energy and the relation to an elements atomic number. Also, in this project I noted relations in the graphs that I made in Excel, some of the relations were periodic and some of them were group trends.
