CHEM 105 Lecture 7: 7- Lecture Wednesday, September 12th
Document Summary
Properties and structures of covalent vs. ionic compounds. Nothing about compounds makes sense except in the light of their elemental composition. Usually insoluble in water but soluble in organic solvents. The original element + the second element + -ide. Name the cation (the metal ion) first a. b. Monoatomic cations have the same name as the element. Cations with multiple valence states named with a roman numeral. Monoatomic anions named by dropping its suffix and adding -ide. Make sure that the name includes the roman numeral if you are aware of a differing charge on the element. Ex: copper (i) chloride and copper (ii) chloride. Many transition metals can exhibit more than one ionic charge. Roman numerals are used to denote the charge of such ions. Do so by adding the subscripts of how many of each element is in the compound. Need to ensure that the elements are in their simplest forms (two subscripts of.
