Question

Directions: Write the formula or name of the following compounds in the space provided. (Please note that some of these compounds do not exist as a stable substance in nature, however the following should serve as a practice exercise in nomenclature.) If provided the name, then you must write the formula. If provided the formula, then you must write the correct name. Indicate IUPAC names only. NOTE: IF EVEN ONE PROBLEM IS LEFT UNANSWERED, YOU WILL RECEIVE ZERO (0) POINTS FOR THIS OPPORTUNITY. Use one of the following descriptions: ionic or covalent.

Answer 1

Salts of alkali and alkaline earth metals are largely ionic in nature. In salts formed by transition metals, when Metal is in higher oxidation state then covalent character increases due to larger polarising power of cation. For example 89) CrS₃  is covalent because Cr is in +6 oxidation state.
