For questions 1 to 5, look at the shape of the graph you made of the first ionization energy.
Where was the line going up (be specific)?
Where was the line going down (be specific)?
Is there a pattern to the first ionization energy?
Describe that pattern in detail.
How many times does that pattern repeat?
For questions 6 to 11, compare the first ionization energy graph to a periodic table
6) How many rows or periods of elements did you graph?
7) What is the relationship between the pattern of the graph and the rows of the periodic table?
8) Rank the ionization energies of Hydrogen (H), Lithium (Li), and Sodium (Na) from highest to
lowest.
9) What happens to ionization energy as you move down the periodic table?
10) Rank the ionization energies of Lithium (Li), Carbon (C), and Neon (Ne) from highest to lowest.
11) What happens to ionization energy as you move across the periodic table from left to right?
For questions 12 to 14, look at the graph you made of the second ionization energy
12) For any particular atom, is the second ionization energy greater or less than the first?
13) How does the shape of the second ionization energy graph compare to the first (be specific)?
14) Why doesn’t Hydrogen have a second ionization energy?
