Protium oxide is the name given to `D_2O.`

Explanation

To determine whether the statement "Protium oxide is the name given to D2O" is correct or not, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Isotopes of Hydrogen**:
- Hydrogen has three isotopes: Protium (¹H), Deuterium (²H), and Tritium (³H).
- Protium is the most common isotope, consisting of one proton and no neutrons.
- Deuterium has one proton and one neutron.
- Tritium has one proton and two neutrons.

2. **Understand the Oxides Formed by These Isotopes**:
- Protium (¹H) forms water, which is known as Protium oxide (H₂O).
- Deuterium (²H) forms deuterium oxide (D₂O).
- Tritium (³H) forms tritium oxide (T₂O).

3. **Analyze the Given Statement**:
- The statement claims that "Protium oxide is the name given to D₂O."
- However, D₂O is actually known as Deuterium oxide, not Protium oxide.

4. **Conclusion**:
- Since D₂O is not referred to as Protium oxide, the statement is false.

### Final Answer:
The statement "Protium oxide is the name given to D₂O" is **false**.
