Question

based on the naming rules for ions, which of the following is a negatively charged ion (not a polyatomic ion)? (1 point)
○ chlorite
○ chlorate
○ chlorine
○ chloride

Explanation:

1. Analyze each option:

• Chlorite ($\ce{ClO2^-}$) and chlorate ($\ce{ClO3^-}$) are polyatomic ions (consist of multiple atoms), so they are eliminated.
• Chlorine ($\ce{Cl2}$) is a neutral diatomic molecule, not an ion, so it is eliminated.
• Chloride ($\ce{Cl^-}$) is a monatomic (single atom) negatively charged ion (anion) formed when chlorine gains an electron.

Answer:

D. chloride
