(a)
Interpretation:
The chemical formula for the following binary ionic compound–Cobalt(II) sulphide is to be written.
Concept Introduction:
An ionic compound has two elements one is metal and another one is non-metal. The metal ion always has positive charge and the nonmetal ion always has negative ion in binary compounds.
Example:
The following rule can be used for the naming of binary ionic compounds.
The full name of the metallic element is given first, followed by a separate word containing the stem of the metallic element name and the suffix –ide.
The positive charge on metal ions from IA, IIA and IIIA is equal to the group number, while the negative charge on non-metal ions from VA, VIA and VIIA is equal to the group number eight.
