7 Part B: Nomenclature of Acids 1. What element always leads the formula of an acid? Hydrogen, which occurs as the H + cation. 2. The names of acids depend on the type of anion they contain. Complete the following table: Name of Anion ends in Name of Acid is ide hydro ic acid ate ic acid ite ous acid 3. Identify and name the anions in the following acids, then name the acids. Acid Formula Anion in Acid Acid Name HBr (aq) Br -1, bromide hydrobromic acid H 3PO 4 (aq) -3 PO 4, phosphate phosphoric acid HClO 2 (aq) -1 ClO 2, chlorite chlorous acid HCN (aq) CN -1, cyanide hydrocyanic acid HMnO 4 (aq) -1 MnO 4, permanganate permanganic acid H 2SO 3 (aq) -2 SO 3, sulfite sulfurous acid 4.

8 Part C: Nomenclature of Simple Binary Covalent Compounds 1. Which of the following non-metals would you write first in a covalent compound's name or formula? oxygen or nitrogen iodine or chlorine silicon or sulfur 2. Write the names or formulas as required for each of the following covalent compounds. Compound Cl 2O 6 CO H 2S ICl 5 N 2F 2 Br 3O 8 XeCl 4 SO 3 Name or Formula dichlorine hexaoxide carbon monoxide hydrogen sulfide iodine pentachloride dinitrogen difluoride tribromine octaoxide xenon tetrachloride sulfur trioxide tetraphosphorus decoxide P 4O 10 tricarbon disulfide C 3S 2 hydrogen iodide HI sulfur heptafluoride SF 7 dichlorine monoxide Cl 2O silicon tetrabromide SiBr 4 dinitrogen pentoxide N 2O 5 3. Why is it necessary to use prefixes in the names of covalent compounds? In covalent compounds, the neutral non-metal atoms involved can combine in a variety of ratios, producing several different compounds (containing the same elements). Thus prefixes are needed in their names to differentiate between these compounds, by indicating the number of atoms of each non-metal atom found in them. 4. In what cases do we not use prefixes in the names of covalent compounds? The prefix "mono" is dropped from the name of the first element when there is only one atom of that element present. Also, no prefixes at all are used in the names of covalent compounds containing hydrogen.
Nomenclature of Ionic Compounds
Nomenclature of Ionic Compounds Ionic compounds are composed of ions. An ion is an atom or molecule with an electrical charge. Monatomic ions are formed from single atoms that have gained or lost electrons.

Monatomic Ions. A. Monatomic Ions In order to determine the charge of monatomic ions, you can use the periodic table as a guide:
Monatomic Ions Ions are atoms that have either lost or gained electrons. While atoms are neutral, ions are charged particles. A loss of electrons results in a positive ion or cation (pronounced cat-eye-on
