Whether the given compounds name are correct or incorrect, is to be checked and if possible all correct possible names along with formula are to be written. Concept Information: Transition metals have the ability to form more than one positive ion and then can form two ionic compounds with given non-metals. To attain an electrically neutral compound, the respective charges of the cation and anion are interchanged, that is, positive charges for the subscript of the anion and negative charges for the subscript of the cation. Stock system is the method for naming the metal ions that have more than one oxidation state in compounds which are indicated by Roman numeral in parenthesis just after the name of the metal ion. For naming of ionic compounds containing polyatomic ions, the name of the metal (cation) or a polyatomic cation written first, followed by the name of anion, this can be non-metal, and it this is non-metal (anion), change the suffix of non-metal to - i d e , adding at the end of the anion, that is in case of monatomic ions. The hydroxide ion and cynide ion are the exceptions. Rules of naming molecular compounds: Replace the ending of the second element with “ide”. While naming molecular compounds prefixes are used to indicate the number of a given element present in the compound like ” mono-” indicates one, “di-” indicates two, “tri-” is three, “tetra-” is four, “penta-” is five, and “hexa-” is six, “hepta-” is seven, “octo-” is eight, “nona-” is nine, and “deca” is ten.

Solution Summary: The author explains that transition metals have the ability to form two ionic compounds with given non-metals. Stock system is the method for naming the metal ions that have more than one oxidation state in compounds.
Definition Definition Elements containing partially filled d-subshell in their ground state configuration. Elements in the d-block of the periodic table receive the last or valence electron in the d-orbital. The groups from IIIB to VIIIB and IB to IIB comprise the d-block elements.

Each of the following names is incorrect. Give the correct names.
(a) CrCl2, chromium(I) chloride(b) Zn(NO3)2, zinc(II) nitrate(c) CrN, chromium(I) nitride
Elements in the same group of the periodic table often form oxyanions with the same general formula. The anions are also named in a similar fashion. Based on these observations, suggest a chemical formula or name, as appropriate, for each of the following ions: (a) BrO4 -, (b) SeO3 2-, (c) arsenate ion, (d) hydrogen tellurate ion.
Each of the following names is incorrect. Give the correct names.
(a) AlCl3, aluminum(III) chloride(b) CrCl2, chromium(I) chloride(c) CrS, chromium(I) sulfide
