  1. Inorganic chemical nomenclature(textbook: 12 - 25)

  2. Noble gases Alkaline earth metals Chalcogens Alkali metals Halogens NONMETALS SEMIMETALS METALS

  3. Electronegativity Oxidation state (oxidation number) Valence Ionic charge - "real electric charge" cations: Na+ Ca2+ Al3+ anions: Cl- SO42-

  4. Chemical formulas We have several types of formulas: (according to the information they contain) 1) Empirical formula 2) Molecular formula 3) "Condensed formula" 4) Structural formula 5) Structural formula showing unshared electrons

  5. 1) EMPIRICAL - relative number of each type of atom (ratio of the elements) - e.g. H2SO4 Al2O3 CH2O 2) MOLECULAR - real number of atoms in the molecule - e.g. H2SO4 Al2O3 C6H12O6 3) "CONDENSED" (functional groups) - characteristic groups of atoms (=functional groups) - e.g. Mg(OH)2 (NH4)2SO4 K4[Fe(CN)6]

  6. 4) STRUCTURAL - types and arrangement of bonds between atoms 5) STRUCTURAL with unshared electrons - shows also unshared (non-bonding) electron pairs

  7. Latin nomenclature (INN) INN = International Nonproprietary Names - intended to be used worldwide for the identification of a given pharmaceutical substance - free of any protection of rights of ownership - recommendations come from World Health Organization (WHO)

  8. "Drug names" TRADE NAME - registered to pharmaceutical company - protection of rights of ownership CHEMICAL NAME - long, difficult GENERIC NAME (INN) – "free" e.g. simvastatinum - trade names in the Czech republic: Zocor, Simgal, Simvor, Vasilip, Simvastatin AL, APO-Simva, ... ... - statinum  drug for lowering cholesterol
