2. Place ( ) around polyatomic ion ONLY IF more than one, then tell how many as subscript outside ( ). 3. This is ionic bonding between metal and polyatomic ion. 4. Covalent bonding holds the polyatomic ion together.NH4ClO= ammonium hypochlorite (NH4)2SO3= ammonium sulfite Type II e Polyatomic Ion + Nonmetal1. Name polyatomic ion them nonmetal, 2. Nonmetal name is changed to the “ide” suffix since it is the anion. NH4F = ammonium fluoride (NH4)2O = ammonium oxide Type III Nonmetal + Nonmetal1. Name as though ionic, even though it is not. This is covalent bonding. 2. Do not try to solve using metal + nonmetal rules. JUST NAME IT USING GREEK PREFIXES. mono =1, di=2, tri=3, tetra =4, penta =5, hexa =6, hepta =7, octa =8, nona =9 deca =10 3. Never use mono for the first element.SO3= sulfur trioxide P2O5= diphosphorus pentoxide Acids & Bases 1. Acids have H written first in the formula. These are the transferable hydrogens. Acids should be denoted by the (aq) state. Acids without oxygen are named hydro___ ic acid. Acids with oxygen are named by looking at the ending of their polyatomic names. If “ate”, then “___ic acid” and if “ite”, then “___ous acid”. Hydro is not used with acids with oxygen in it. 2. Bases can be easily recognized when the hydroxide ion (OH-) is observed. Ammonia (NH3) is also a base. HCl (aq) = hydrochloric acid H2SO4(aq) = sulfuric acid HNO2(aq) = nitrous acid HYDRATES (hydrate = H2O associated with complex)1. Name the compound as noted above. 2. Tell how many hydrates using Greek prefixes. 3. Place a dot (.) between complex and hydrate. 3. Mono is used to indicate only one hydrate. NaNO3.H2O = sodium nitrate monohydrate Sn(ClO3)2.7 H2O =tin (II) chlorate heptahydrate (IUPAC System) or stannous chlorate heptahydrate (Classical System)
