1. Journal: Choose one of these Periodic Table ideas or come up with your own.
Explain what different CATEGORIES/SECTIONS you would make to group your “Elements” by similarities (ex. Heroes section, villains section)
Explain what TRENDS you would create in your table (ex. Characters on the far left are terrible villains, as we go right they get less bad, and the far right side is amazing heroes OR hair color is light in the top rows and gets darker as we go down rows)

Linus Pauling ( ) awarded Nobel Prize in chemistry in 1954 for his 1939 text, The Nature of the Chemical Bond,
and also won the Nobel Peace Prize in 1962 for his fight to control nuclear weapons.
The greater the electronegativity of an atom in a molecule, the more strongly it attracts the electrons in a covalent bond. 7

Metals have low ionization energy; nonmetals have high ionization energy.
This experimental data gives evidence for:
1) effect of increasing nuclear charge
2) stability of octet
3) effect of increased radius
4) s & p sublevel in outer level
SUGGESTION: Emphasize that theories came from experimental evidence! K
