The sum of the number of neutrons and protons in the isotopes of hydrogen is

Options

A. 6
B. 5
C. 4
D. 3

Explanation

To find the sum of the number of neutrons and protons in the isotopes of hydrogen, we will follow these steps:

### Step 1: Identify the isotopes of hydrogen
Hydrogen has three main isotopes:
1. Protium (¹H)
2. Deuterium (²H)
3. Tritium (³H)

### Step 2: Determine the number of protons and neutrons in each isotope
- **Protium (¹H)**:
- Protons: 1
- Neutrons: 0
- Sum = 1 (proton) + 0 (neutron) = 1

- **Deuterium (²H)**:
- Protons: 1
- Neutrons: 1
- Sum = 1 (proton) + 1 (neutron) = 2

- **Tritium (³H)**:
- Protons: 1
- Neutrons: 2
- Sum = 1 (proton) + 2 (neutrons) = 3

### Step 3: Calculate the total sum of protons and neutrons for all isotopes
Now we will add the sums from each isotope:
- Protium: 1
- Deuterium: 2
- Tritium: 3

Total Sum = 1 (Protium) + 2 (Deuterium) + 3 (Tritium) = 6

### Final Answer
The sum of the number of neutrons and protons in the isotopes of hydrogen is **6**.
