Concept explainers
Interpretation:
The blank table should be filled.
Concept introduction:
Anion: negatively charged atom or a molecule is called anion and it has more number of electrons.
Cation: positively charged atom or a molecule is called cation and it has less number of electrons.
Naming the ions and ionic compound:
A monoatomic cation is named by adding the word ion to the name of the element. Therefore, the ion of potassium
Some of the metal such as manganese (Mn) will form cations with three or more different charges. Therefore Roman numeral is used for the giving name for the inorganic compound. Roman numeral I indicates one positive charge, II means two positive charge, and so on.
For example,
A monoatomic anion is ending with –ide along with ion, therefore, the anion of chlorine (
