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.
