When is the oxidation state of a metal indicated in the name of a compound?A.When a prefix is used to indicate the number of metal atomsB.When the metal can exist in more than one oxidation stateC.When the charge on the nonmetal is not knownD.When the compound being named is a covalent compound

The oxidation number of the metal is written in parentheses, in Roman numerals following the name of the transition metal.Fill in the missing information to complete the names of the coordination compounds/complexes shown below.

Why are prefixes used in naming covalent compounds?A.The atoms can have different numbers of valence electrons.B.The same atoms can combine in more than one ratio.C.Oxidation states of the atoms are identified with prefixes.D.The prefixes identify the only way the atoms can combine.

Which metal is not required to have its charge specified in the names of ionic compounds it forms?Group of answer choicesFeMnCaCu

Name the following compound. If the cation requires an oxidation state (Roman numerals), then make sure you put the name of the cation and the Roman numerals without a space in between, like iron(II) or copper(I).KC2H3O2

Under Ionic or Covalent write in a "i" for ionic and a "c" for covalent.  The next two blanks under name write the name of the compound. For the name of the compound. If the metal requires a Roman numeral, then make sure you put the name of the cation(metal) and the Roman numerals without a space in between them and use parenthesis around the roman numeral, like this:   iron(II) or copper(I) Formula PbSO4ionic or covalent Name
