The Periodic Table of Elements
Let's Prep | Warm Up
Metals, Nonmetals and Metalloids
Warm Up | Prep
1. Observe the periodic table you were given . Find at least 3 patterns and explain why you think it is a pattern.
2. An atom of Oxygen has an atomic number of 8. Based on this information, how many protons does this atom have? Electrons?
3. Phil thinks that water is a compound, but Marcel thinks water is an element. In 3 sentences or less, determine who is correct and 2 reasons WHY.
Definition:
Metal: easily conducts heat & electricity,
luster, ductile, malleable
Nonmetal: lack metallic properties, NOT
conductors of heat and electricity;
Insulators, brittle
Metalloid: Properties of both M and NM...
Semiconductors!
Examples:
Metal: Ni (nickel)
Nonmetal: Kr (Krypton)
Metalloid: As (Arsenic)

Periodic Table Foldable
Reactive vs. Nonreactive
1. Cut AROUND the whole BIG box (leave all 6 squares together).
2. Cut the HORIZONTAL long line.
3. Lay "METALLOID" as your base on the table.
4. Fold (like a fan) the remaining pieces together.
5. Put a small piece of tape to join non-reactive and metal together.
Definition:
Reactive Element: Easily/readily responds (joining, repelling, forming a new substance) to other elements.
Nonreactive Element: Does not respond noticeably to the presence of other elements.
Example: Na and K are stored in bottles because they are highly reactive especially with Oxygen that's why they keep it in a bottle.
Groups vs. Period
Definitions:
Groups ( 18 periods)
Periods ( 7 rows)
Arranged according to:
Groups: similar properties
Periods: increasing atomic number
