1. Activity #31: The Periodic Table Ways the Periodic Table is Organized
Color code your periodic table by family like the one below. You will need 9 colors- they do not have to be the same as those in the picture. Make a key that shows which color represents which family of elements.
Periodic Table Families
Alkali Metals
Alkaline Earth Metals
Transition Metals
Rare Earth Elements
Noble Gases
Metalloids
Halogens
Non Metals
Other Metals

2. Activity #31: The Periodic Table Ways the Periodic Table is Organized
Take Cornell Notes on the following ways the periodic table is organized. Be sure to give examples as well as the definition:
Family
Metals, Nonmetals, and
Metalloids
Groups
Periods
Reactivity
Atomic Number

3. Ways the Periodic Table is Organized
Family- Elements grouped together by properties.
Ex. Alkali metals, Halogens, Noble gases…etc.

4. Ways the Periodic Table is Organized
Metals: shiny, easily shaped, good conductor of electricity and heat
Non metals: has properties generally opposite of metals
Metalloids: elements that have properties of metals and non metals

5. Ways the Periodic Table is Organized
Groups- vertical columns, elements have similar physical properties; Ex. Group 1 contains Hydrogen, Lithium, Sodium, etc.
** Number the groups across the top of your periodic table!

6. Ways the Periodic Table is Organized
Periods- horizontal rows, a proton is added to each element from left to right; ex. Period 2 contains Lithium, Beryllium, Boron, etc.
** Number the periods on the left side of your periodic table!

7. Ways the Periodic Table is Organized
Reactivity- how likely an element is to undergo a chemical change; Elements in groups 1 and 17 are highly reactive and chemically react easily with other elements
(video on Halogens from Group 17)

8. Ways the Periodic Table is Organized
Atomic Number- the number of protons in the nucleus of an atom; the atomic number increases from left to right; Ex: the atomic number of Hydrogen is 1, Helium 2, Lithium 3….
