SWBAT: Understand how
the periodic table is arranged
Period 3 BellringerFind the group and period for:
NitrogenManganeseLithium
Three Categories: 1) Metals:
Usually shiny
Malleable and ductile
Conducts heat and electricity.
Shown in Blue!!
Categories:
2) Nonmetals:• Colorful, can be
dull
• Brittle, Hard or Soft
• Poor Conductors
• .
Shown in Yellow!!
3) Metalloids:
- have properties of both metals and nonmetals.
Ex. Silicon - Shiny-Not malleable or ductile-Brittle-Poor conductors compared to metals but better than nonmetals.
Shown in Pink!!
MetalloidsSometimes called the “stairstep elements”
We will be memorizing them!Boron (B)Silicon (Si)Germainium (Ge)Arsenic (As)Antimony (Sb)Tellerium (Te)Astatine (At)
Period 2 Bell ringer
Find the element:
Period 6, Group 11
List 3 properties of metalsList 2 properties of nonmetalsDescribe the properties of metalloids

The Periodic TableSWBAT: -Classify elements into families-Describe the characteristics of each family
Families on the Periodic Table
Columns are also grouped into families.
Families may be one column, or several columns put together.
Families have names rather than numbers. (Just like your family has a common last name.)
Alkali Metals1st column on the periodic table (Group 1) not including hydrogen.
(Colored Orange)
Very reactive metals, always combined with something else in nature (like in salt).
Soft enough to cut with a butter knife
Alkaline Earth Metals
Second column on the periodic table. (Group 2)
Colored Yellow
Reactive metals that are always combined with nonmetals in nature.
Several of these elements are important mineral nutrients (such as Mg and Ca
Transition Metals
Elements in groups 3-12
Colored Pink
Less reactive harder metals
Includes metals used in jewelry and construction.
Metals used “as metal.”
HalogensElements in group 17
(Colored green)
Very reactive, volatile, diatomic, nonmetals
Always found combined with other element in nature .
Used as disinfectants and to strengthen teeth.
The Noble Gases
Elements in group 18
Colored Blue
VERY unreactive, monatomic gases
Used in lighted “neon” signs
Used in blimps to fix the Hindenburg problem.
