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

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

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

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

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.

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

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

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

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

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

Rare Earth Metals Valence numbers Vary All are metals Lanthanides (elements 58-71) Actinides (elements 90-103) 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
