Olivia Corby Period 1 Fundamentals of Chemistry ALLOTROPES Olivia Corby Period 1 Fundamentals of Chemistry

DEFINITION one of two or more existing forms of an element Periodic Table of the Elements Source : http://dictionary.reference.com/browse/allotrope

ALLOTROPES OF CARBON diamonds graphite http://en.wikipedia.org/wiki/Allotropes_of_carbon

ALLOTROPES OF OXYGEN dioxygen ozone Diagram of the layers of the earth-specifically ozone layers http://en.wikipedia.org/wiki/Allotropes_of_oxygen

ALLOTROPES OF IRON stainless steel BBC THREE TYPES OF IRON ALLOTROPES: -alpha -gamma -delta http://en.wikipedia.org/wiki/Allotropes_of_iron

USES/APPLICATIONS Diamonds-jewelry (rings, bracelets, necklaces, earrings, etc.) Graphite-pencils Stainless steel-buildings, silverware, pipes, etc.

HOW DOES THIS RELATE TO CLASS? Balancing chemical equations-the product is a result of a compound which produces a brand-new substance In order to create allotropes, substances sometimes need to be heated up or cooled down which is an example of a physical property Because we have been studying the Periodic Table and understand how some of the elements are grouped, we can make connections to how some allotropes are formed

REVIEW QUESTIONS What are 2 uses for any allotropes? Ozone is an example of what kind of element allotrope?
