Nomenclature Thinking
1.
Identify the type of each of the following compounds and explain why you know.
a. MnO2 
Type II, manganese is a metal with multiple oxidation states
b. SCl4

Type III, sulfur is a nonmetal
c. IrO2

Type I, iridium is a metal with a single oxidation state
d. Carbon tetrachloride 
type III, prefix tetra used in type III
e. Beryllium iodide
type I, no prefix or roman numeral

f. Cobalt (III) bromide 
type II, roman numerals used only in type II
2.
A compound that contains a polyatomic can be what type of compound? Why?
Only type 1 and 2, polyatomics are ions
Type 3 compounds are covalently bonded and have no ions
3.
Can a compound be comprised of two metal ions?
Nope, metals for cations and two positive ions won’t stick together
4.
Identify what’s wrong with each of the following and fix them:
a. PdS2 is palladium (II) sulfide
its palladium (IV) sulfide
b. Osmium (IV) oxide
osmium is only Os+4 so its type I, osmium oxide
c. Mononitrogen dioxide
type 3 can not start with mono, nitrogen dioxide
d. Phosphide monoxide
no –ide on first element, phosphorus monoxide
e. Dinitrogen carbonate
no polyatomic ions in type 3 compounds (no fix)
