Interpretation: The similarities and differences between polyatomic ions and monatomic ions are to be stated.
Concept Introduction : There are two types of charged species, anion (negatively charged species) and cation (positively charged species). Anion is formed by the gaining of an electron whereas a cation is formed by losing an electron. But there is no change in the protons or, in other words, protons remain the same.
Answer to Problem 4LC
Polyatomic ions and monoatomic ions both are charged species, but polyatomic ions are composed of two or more atoms and monoatomic ions are composed of only a single atom.
Explanation of Solution
The similarities between polyatomic ions and monoatomic ions are:
- Both are charged species and formed by gaining or losing electrons.
The differences between polyatomic ions and monoatomic ions are:
- Polyatomic ions are charged species that are composed of two or more atoms, but monoatomic ions are composed of only a single atom.
