Document Summary
3 #"s 7, 11, 25, 27, 33, 35, 41, 49, 51, 57, 59, 61. Molecular structure and naming molecules: their names are all related to their function and can be derived from a systematic name. Nomenclature: divides molecules in organic or inorganic, any molecule that has c or h is organic, exceptions do occur for example carbonic acid is inorganic (h2co3) Oxidation state or oxidation number and the periodic table. The valence shell electrons do the bonding, they can be found from their place on the periodic table. Oxidation state is the number of electrons gained or lost by an element. Compounds must be neutral so that"s why we switch the subscripts because there has to be an equal number of electrons that are being gained or lost. H2co3 is inorganic because in the way that it is structured carbon is only bonded to oxygen and no hydrogens. Binary compounds: a compound formed from two elements only.
