Title: Families on the Periodic Table
1Families 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.
2Properties 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
4ALKALI 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
5ALKALINE 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
6TRANSITION 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
7Mixed 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
8Lanthanides 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
94.4 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.
10What 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
12Nonmetals are orange- dont forget Hydrogen
Color the nonmetals blue- dont forget hydrogen
13Metalloids
- 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
