Question

What is the primary distinction between a monatomic ion and a polyatomic ion?
Options
A Monatomic ions are always positively charged, while polyatomic ions are always negatively charged.
B Monatomic ions consist of a single atom with a charge, while polyatomic ions consist of two or more atoms with a net charge.
Correct Answer
C Monatomic ions are found only in metallic elements, while polyatomic ions are found only in nonmetallic elements.
D Monatomic ions can only exist in solid state, while polyatomic ions can only exist in solution.
Correct Answer

Option B is the correct answer.

Detailed Explanation

A monatomic ion is formed from a single atom that has gained or lost electrons (e.g., Cl-, Na+). A polyatomic ion is a group of atoms covalently bonded that together have an overall net charge (e.g., NO3-, NH4+).

Hint

Focus on the number of atoms that make up the ion.
