Concept explainers
(a)
Interpretation:The name of the compound
Concept introduction:Combination of cation with respective anion generates an ionic compound. While giving names these ionic compounds, one has to follow certain simple rules. The cation’s name is always written first followed by anion’s name. Cation’s name is same as its elemental name however in anion’s name, the suffix “ide” is substituted at the end part of its element’s name.
