2. 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.
There are 11 families

3. ALKALI METALS Group 1 Hydrogen is NOT a member, it is a non-metal
1 Valence Electron
All metals
Extremely reactive, esp. with water
Most reactive metals
Conduct electricity and heat
Low densities
Soft and silvery
Examples: Salt/Photography

4. ALKALINE EARTH METALS Group 2 2 Valence Electrons All Metals
Reactive, but less than Alkali metals
White, silvery and malleable
Conduct electricity and heat
Higher densities than alkaline metals
EXAMPLES: foods, cement, chalk, vitamins

5. TRANSITION METALS Groups 3-12 Most have 1 or 2 valence electrons
All Metals
Reactive, but less reactive than group 2
Can bond with many elements in a variety of shapes.
Good conductors of heat and electricity.
Some are used for jewelry or coins
Shiny
EXAMPLES: jewelry, thermometers, coins

6. BORON FAMILY Group 13 3 Valence Electrons
Most are metals, Boron is a metalloid
Reactive, but not as much as group 1 and 2
Solid at room temperature
Properties begin to vary among elements
EXAMPLES: Aluminum is the most abundant metal in the Earth’s crust and used in airplane parts.

7. CARBON FAMILY Group 14 4 Valence Electrons
Contains metals (Sn & Pb), metalloids (Si & Ge), and a non-metal (C)
Reactive
Properties vary among elements
Solid at room temperature
EXAMPLE: Carbon is in all living things and even some nonliving things like diamonds and fossil fuels
CARBON FAMILY

8. NITROGEN FAMILY Group 15 5 Valence Electrons
Contains metals (Bi), metalloids (As & Sb), and non-metals (N & P)
Reactive
Properties vary among elements
Solid at room temperature except N (gas)
EXAMPLE: Nitrogen is 80% of the air we breathe

9. OXYGEN FAMILY Group 16 6 Valence Electrons
Contains metalloids (Te & Po), and non-metals (O, S & Se)
Reactive
All but Oxygen are solid at room temperature
EXAMPLES: air (Oxygen) and H2SO4 is the most widely used compound in industry

10. Halogens Group 7 7 Valence Electrons All are non-metals
Very reactive are often bonded with elements from Group 1 in the form of salts
Most reactive Nonmetals
Never found pure in nature
EXAMPLES: Many are used in salts and disinfectants

11. Noble Gases Group 8 8 Valence Electrons = Full
Helium (He) has only 2 electrons in the outer shell = Full
All Non-metals
Not reactive with other elements - INERT
Exist as colorless, and odorless gases
EXAMPLES: Lights & blimps

12. Rare Earth Metals Valence numbers Vary All are metals
Lanthanides (elements 58-71)
Actinides (elements )
They are reactive
Some are Radioactive
Silver, silvery-white, or gray metals
Conduct electricity
EXAMPLES: Some used to create electricity and some are used in smoke detectors
