Families on the Periodic Table

1
Families on the Periodic Table

• Elements on the periodic table can be grouped
  into families bases on their chemical properties.
• Each family has a specific name to differentiate
  it from the other families in the periodic table.
• Elements in each family
• react differently with
• other elements.

Properties of Metals

• Metals are elements that are good conductors of
  electric current and heat. They tend to be shiny
  and bendable.
• Physical Properties-
• 1. Luster- shiny and reflective
• 2. Malleable- can be hammered or rolled
• 3. Ductile- can be pulled out or drawn into long
  wires
• 4. Thermal conductivity- ability of an object to
  transfer heat
• 5. Electrical conductivity- ability of an object
  to carry electric current

3

• Chemical Properties-
• 1. Reactivity- the ease and speed an element
  combines or reacts with other substances
• 2. Corrosion- the deterioration of a metal

ALKALI METALS

• Group 1
• Hydrogen is not a member, it is a non-metal
• All are metals and solid at room temp
• 1 Valence Electron
• Soft and silvery, shiny
• Very reactive, esp. with water
• Conduct electricity

Color the Alkali metals pick
5
ALKALINE EARTH METALS

• Group 2
• Metals
• Solids at room temp
• 2 electrons in the outer shell
• White, silvery, and malleable
• Reactive, but less than Alkali metals
• Conduct electricity

Color the Alkaline Earth Metals purple
6
TRANSITION METALS

• Metals
• Almost all are solids at room temp (Hg)
• Good conductors of heat and electricity.
• 1 or 2 Valence Electrons
• Less Reactive than Alkali and Alkaline Earth
• Can bond with many elements in a variety of
  shapes.

Color the transition metals blue
7
Mixed Metals

• Group 3
• 3 electrons in the outer shell
• Most are metals
• Boron is a metalloid-is acts like a metal and a
  non-metal
• Reactive
• Solid at room temp

The dark blue are the mixed metals.
Color your mixed metals orange
8
Lanthanides and Actinides (Rare Earth Metals)

• Some are Radioactive
• The rare earths are silver, silvery-white, or
  gray metals.
• Conduct electricity
• Many of the actinides are not found in nature,
  only made in labs

Color the lanthanides yellow and the actinides red
9
4.4 Nonmetals and Metalloids

• Physical properties of nonmetals
• They lack the properties of metals
• Poor conductors of electric current and heat
• Dull and brittle
• Low densities
• Most are gases at room temperature
• Chemical properties
• They will gain or share electrons when they react
  with other atoms.

10
What are the Families containing Nonmetals???

• In Group 14, carbon is the only nonmetal.
• In Group 15, nitrogen and phosphorus are the two
  nonmetals.
• In Group 16, oxygen, sulfur, and selenium are the
  three nonmetals.
• Group 17, contains the nonmetals fluorine,
  chlorine, bromine, and iodine. These are also
  known as Halogens, which means salt forming.
  These are very reactive!

11

• Noble Gases- Group 18, they do not form compounds
  because they do not gain, lose, or share
  electrons. They are usually nonreactive.

Color the noble gases gold
12
Nonmetals are orange- dont forget Hydrogen
Color the nonmetals blue- dont forget hydrogen
13
Metalloids

• Between the metals and nonmetals lie the
  metalloids.
• They have some properties of metals and some
  properties of nonmetals.
• Solid at room temperature
• Brittle, hard, and somewhat reactive
• Great conductors of electric current

Color the metalloids green
