Periodic
table can
be divided
into 3
categories.
1
Created by Campesi, SMS
Metals:
Good
conductors
of heat,
malleable,
ductile,
shiny, few
electrons in
outer
energy level
2
NONMETALS
poor conductors
of heat, not
malleable or
ductile, not
shiny, almost
complete set
of electrons in
outer energy
level
3
Metalloids
also called
semiconductors
have properties
of both
4
(Mark the stairstep on your periodic table.)
Most elements are metals which
are found to the left of the
5
stairstep.
• Horizontal rows are
called periods.
• Vertical rows are called
groups.
6
Group #1: Alkali Metals
Group contains: metals
Electrons in outer level: 1
Reactivity: very reactive!
Other properties: Soft,
silver-colored, shiny, low
density
7
(Pick a color, make a key then color the Alkali Metals.)
8
• Group #2: Alkaline-earth
metals
• Group contains: metals
• Electrons in the outer level: 2
• Reactivity: very reactive but
less than Alkali
• Other properties: silvercolored, more dense than
alkali metals
9
Add Alkaline metals to your key and color.
10
Groups #3-12: Transition metals
Group contains: Metals
Electrons in the outer level: 1 or 2
Reactivity: Less reactive than
alkaline-earth metals
Other properties: Shiny, good
conductors, higher densities and
melting points
11
Add Transition metals to your key and color.
12
• Lanthanides:
follow lanthanum
similar properties
• Actinides: follow
actinium, all atoms
are radioactive,
which means they
are unstable.
13
Add Lanthanides to your key and color.
Add Actinides to your key and color.
14
• Metalloids, also
called
semiconductors.
• Have properties of
both metals and
nonmetals.
• Have ½ a complete
set of electrons.
15
Put dots in the middle on your metalloids and add it to
your key.
16
• Group #13: Boron group
• Group contains: 1 metalloid
and 4 metals
• Electrons in the outer level:
3
• Reactivity: reactive
• Other shared properties:
Solid at room temp
17
Add the Boron group to your key and color.
18
• Group #14: Carbon group
• Group contains: 1 non, 2
metalloids, 2 metals
• Electrons in the outer
level: 4
• Reactivity: varies
• Other shared properties:
solid at rm temp.
19
Add the Carbon group to your key and color.
20
• Group # 15: Nitrogen group
• Group contains: 2 non, 2
metalloids, 1 metal
• Electrons in the outer level: 5
• Reactivity: varies
• Other shared properties: all
but nitrogen are solid at room
temp.
21
Add the Nitrogen group to your key and color.
22
• Group #16: Oxygen group
• Group contains: 3 non, 1
metalloid, 1 metal
• Electrons in the outer level: 6
• Reactivity: varies
• Other shared properties: all
but oxygen are solids at room
temp.
23
Add the Oxygen group to your key and color.
24
• Group #17: Halogen group
• Group contains: nonmetals
• Electrons in the outer level: 7
• Reactivity: VERY reactive
• Other shared properties: poor
conductors, react violently
with alkali metals, never found
alone in nature
25
Add the Halogen group to your key and color.
26
• Group # 18: Inert or Noble
gases
• Group contains: nonmetals
• Electrons in outer level: 8
• Reactivity: unreactive
• Other shared properties:
colorless, odorless gases at
room temp.
27
Add the Inert or Noble gases group to your key and color.
28
• Hydrogen stands alone!
• Electrons in outer level: 1
• Other properties:
colorless, odorless gas at
room temp., low density,
reacts explosively with
oxygen
