Organic Chemistry concept map
Organic Chemistry Is made of Is used in Is the study of the structure, properties, composition, reactions, and preparation of carbon-based compounds. Chemical compounds Elements Which always contain Carbon Plastics Drugs Foods All living things It provides Which are usually Meltable and can be boiled Hydrophobic Is able to have Many bonds shared with the carbon atom. Different types of organic molecules including things that make up hair, skin, and fingernails. Due to The versatility of carbon?s bonds. Structure for living things. Which helps Many combinations of compounds to be possible. The variation within organisms that make up blocks of life. Contributes to Many different possible substances. http://www.visionlearning.com/library/module_viewer.php?mid=60

Chemistry notes (metals)
Unit 8 Topic 2 Metals form ionic compounds with nonmetals. The formulas for these compounds are determined by balancing out the positive charge of the metal ion and the negative charge of the nonmetal. The names of these compounds are determined by using the name of the metal followed by the nonmetal with an ?ide? ending or the name of the polyatomic ion. Alkali metals (group 1) form ions with a +1 charge. When combining with elements from group 17 (halogens) they combine in a 1:1 ratio of metal (+1) to nonmetal (-1). Li+1 + F-1 ( LiF lithium fluoride Na+1 + Br -1 ( NaBr sodium bromide Cs+1 + I-1 ( CsI cesium iodide When combining with elements from group 16 they combine in a 2:1 ratio of metal (+1) to nonmetal (-2). K+1 + O-2 ( K2O potassium oxide
