Title: 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.

2
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

4
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
