Question 10 of 43 \( { }^{n c} \) Classify each of the ions as monoatomic or polyatomic. Monoatomic ions Polyatomic ions Answer Bank \( \mathrm{CN}^{-} \) \( \mathrm{PO}_{3}^{3} \) - \( \mathrm{Li}^{+} \) \( \mathrm{IO}_{4}^{-} \) \( \mathrm{Cl}^{-} \) \( \mathrm{Mg}^{2}+ \) \( \mathrm{H}_{3} \mathrm{O}^{+} \) \( \mathrm{Hg}_{2}^{2}{ }^{+} \) \( \mathrm{Sn}^{2}+ \) \( \mathrm{Cu}^{+} \) \( s^{2-} \)

Certainly! Here's the classification of each ion into **Monoatomic** and **Polyatomic** categories: --- ### **Monoatomic Ions** These ions consist of a single atom with a positive or negative charge. - **\( \mathrm{Li}^{+} \)** (Lithium ion) - **\( \mathrm{Cl}^{-} \)** (Chloride ion) - **\( \mathrm{Mg}^{2+} \)** (Magnesium ion) - **\( \mathrm{Sn}^{2+} \)** (Tin(II) ion) - **\( \mathrm{Cu}^{+} \)** (Copper(I) ion) - **\( \mathrm{S}^{2-} \)** (Sulfide ion) --- ### **Polyatomic Ions** These ions consist of two or more atoms bonded together, carrying an overall charge. - **\( \mathrm{CN}^{-} \)** (Cyanide ion) - **\( \mathrm{PO}_{3}^{3-} \)** (Phosphite ion) - **\( \mathrm{IO}_{4}^{-} \)** (Periodate ion) - **\( \mathrm{H}_{3}\mathrm{O}^{+} \)** (Hydronium ion) - **\( \mathrm{Hg}_{2}^{2+} \)** (Mercury(I) ion) --- #### **Summary** **Monoatomic ions:** - \( \mathrm{Li}^{+} \) - \( \mathrm{Cl}^{-} \) - \( \mathrm{Mg}^{2+} \) - \( \mathrm{Sn}^{2+} \) - \( \mathrm{Cu}^{+} \) - \( \mathrm{S}^{2-} \) **Polyatomic ions:** - \( \mathrm{CN}^{-} \) - \( \mathrm{PO}_{3}^{3-} \) - \( \mathrm{IO}_{4}^{-} \) - \( \mathrm{H}_{3}\mathrm{O}^{+} \) - \( \mathrm{Hg}_{2}^{2+} \) --- This classification helps in understanding the nature of compounds and their behavior in various chemical reactions.
