Coloring the Periodic Table Families

Families on the Periodic Table Elements are grouped into families bases on their chemical properties. Each family has a specific name Elements in each family react differently with other elements of other families.

ALKALI METALS Group 1 or IA Starts with lithium not hydrogen All metals Soft and silvery metals Very reactive, esp. with water Conduct electricity 1 electron in the last orbit Image: http://www.learner.org/interactives/periodic/groups2.html

ALKALINE EARTH METALS Group 2 or IIA Starts with Berelium All metals White and malleable(stretched or bent) Reactive, but less than Alkali metals Conduct electricity 2 electrons in last orbit

TRANSITION METALS Groups IB-VIIIB or 3-12 Good conductors of heat and electricity. All metals Used to make things, specially jewellery. Forms bright colored solutions VIII B is split into three groups.

BORON FAMILY Group 3 or IIIA Starts with Boron. Boron is a metalloid Rest of them are metals. 3 electrons in last orbit

CARBON FAMILY Group 4 or IVA Starts with carbon which is non metal. Followed with Si and Ge which are metalloids Ends with metals Tin and Lead. 4 electrons in the last orbit

NITROGEN FAMILY Group 5 or VA Starts with Nitrogen-nonmetals Followed by Aresenic-metalloid Ends with Bismuth-metals 5 electrons in the last orbit

OXYGEN FAMILY Group 6 or VIA Starts with Oxygen-nonmetal Telurium-metalloid Ends with metal 6 electrons in the last orbit

Halogens Group 7 or VIIA Starts with Hydrgen All are non-metals Very reactive elements Quickly forms bonds with Group 1 elements 7 electrons in the outer shell

Noble Gases Group 8 or VIIIA Exist as gases Non-metals 8 electrons in the outer shell = Full Helium (He) has only 2 electrons in the outer shell = Full Not reactive with other elements

PERIODS There are 1-7 periods Period 6 and 7 are split into: Lanthanide series Actinide series

Rare Earth Metals Some are Radioactive The rare earths are silver, silvery-white, or gray metals. Conduct electricity
