# Periodic Table

Purpose
Determine the trends, if they exist, for atomic size and ionization energy in the Periodic Table.

Materials
Graph paper or Excel spreadsheet

Procedure
1.Use the information from the section of the periodic table. Be sure to give each graph a title and to label each axis.
2.For elements 3-20, make a graph of atomic radius as a function of atomic number. Plot atomic number on the X-axis and atomic radius on the Y-axis.
3.For elements 3-20, make a graph of ionization energy as a function of atomic number. Plot atomic number on the X-axis and ionization energy on the Y-axis.
4.For elements in Family 1A (1) and Family 2A (2), graph Atomic Radius vs. the period number. Use a different color or symbol for each line. Plot Period number on the X-axis and atomic radius on the Y-axis.
5.For elements in Family 1(1A) and Family 2 (2A), graph ionization energy vs period number. Use a different color or symbol for each line. Plot ionization energy on the Y-axis and period number on the X-axis.

Analysis
1.What happens to the atomic radius as the atomic number increases across a period? Down a family? Cite specific examples from your graph to explain your responses.
2. What happens to the ionization energy as the atomic number increases across a period? Down a family? Cite specific examples from your graph to explain your responses.
3.Why does atomic radius change as it does?
4.Why does the ionization energy change as it does?
5.Indicate the element in each set that has higher ionization energy and explains your answer.
a.Rb, Sr, Sn

b.I, F, Br

6.Indicate the element in each set that has the larger atomic radius and explains your answer.
a.Ca, Sr, Be

b.Si, P, S
