The mass of the neutron is of the order of

Options

A. `10^(-23)kg`
B. `10^(-24)kg`
C. `10^(-26)kg`
D. `10^(-27)kg`

Answer

To determine the mass of a neutron and express it in the correct order, follow these steps:

### Step 1: Understand the Mass of Subatomic Particles
- The mass of a neutron is a fundamental property of this subatomic particle. It is important to compare it with the masses of other particles such as protons and electrons.

### Step 2: Identify the Mass of a Neutron
- The mass of a neutron is approximately \(1.675 \times 10^{-27}\) kg. This value is crucial for understanding the relative masses of subatomic particles.

### Step 3: Compare with Other Particles
- The mass of a proton is approximately \(1.673 \times 10^{-27}\) kg, and the mass of an electron is about \(9.1 \times 10^{-31}\) kg.
- From these values, we can see that the mass of a neutron is greater than that of both the proton and the electron.

### Step 4: Determine the Order of Magnitude
- The order of the mass of the neutron can be expressed in scientific notation. Since the mass is \(1.675 \times 10^{-27}\) kg, we can say that the order of the mass of the neutron is \(10^{-27}\) kg.

### Conclusion
- Therefore, the mass of the neutron is of the order of \(10^{-27}\) kg.
