Determine whether the given name for each ionic compound is correct or not. C o I 2 CoIX2: cobalt(II) iodide Correct name B a C l 2 BaClX2: barium dichloride Correct name C s 2 O CsX2O: cesium oxide Choose... R b 2 S RbX2S: rubidium sulfite Correct name S r B r 2 SrBrX2: strontium(II) bromide Incorrect name

: cobalt (II) iodide : correct

: barium di chloride : incorrect

: cesium oxide: correct

: rubidium sulphite : incorrect

: strontium (II) bromide : correct

Explanation:

The nomenclature of ionic compounds is given by:

1. Positive is written first followed by the oxidation state of metal in roman numerals in parenthesis.

2. The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.

Hence, the name of is cobalt (II) iodide, is barium (II) chloride, is cesium oxide, is rubidium sulphide and is strontium (II) bromide.
