Emission is caused by the transformation of one neutron into a proton. This results in the formation of a new element having

Options

A. Same nuclear charge
B. Very lower nuclear charge
C. Nuclear charge higher by one unit
D. Nuclear charge lower by one unit

Explanation

To solve the question regarding the transformation of a neutron into a proton and the resulting changes in nuclear charge, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Understanding the Transformation**:
- A neutron (n) in the nucleus of an atom can transform into a proton (p). This process is known as beta decay.
- During this transformation, a beta particle (which is an electron) is emitted.

2. **Change in Nuclear Composition**:
- Initially, the nucleus has one neutron and one proton. After the transformation, it will have two protons and no neutrons.
- The atomic number of an element is defined by the number of protons in its nucleus.

3. **Effect on Atomic Number**:
- Since a neutron has changed into a proton, the atomic number of the element increases by 1.
- This means that the element is transformed into a new element with a higher atomic number.

4. **Change in Nuclear Charge**:
- The nuclear charge is determined by the number of protons in the nucleus.
- Since one neutron has been converted into a proton, the nuclear charge has increased by one unit.

5. **Conclusion**:
- Therefore, the correct conclusion is that the nuclear charge has increased by one unit due to the transformation of a neutron into a proton.

### Final Answer:
The new element formed has a nuclear charge higher by one unit.
