(a)
Interpretation:
Whether hydronium ion is classified as a monoatomic cation, polyatomic cation, monoatomic anion, or polyatomic anion is to be stated.
Concept introduction:
The species which is formed by losing one or more electrons from a neutral atom is known as a cation. A cation is a positively charged species.
The species which is formed by gaining one or more than one electrons by a neutral atom is known as an anion. An anion is a negatively charged species.
(b)
Interpretation:
Whether strontium ion is classified as a monoatomic cation, polyatomic cation, monoatomic anion, or polyatomic anion is to be stated.
Concept introduction:
The species which is formed by losing one or more than one electrons from a neutral atom is known as a cation. A cation is a positively charged species.
The species which is formed by gaining one or more than one electrons by a neutral atom is known as an anion. An anion is a negatively charged species.
(c)
