Options

A. Positron
B. Neutron
C. Electron
D. Proton

Answer

To solve the question regarding the formation of Carbon-14 from Nitrogen-14 in the upper atmosphere, we can break it down into a series of steps:

### Step 1: Identify the Elements Involved
We start with Nitrogen-14 (N-14) and want to find out how it transforms into Carbon-14 (C-14).

### Step 2: Understand the Process
In the upper atmosphere, Nitrogen-14 can interact with a fundamental particle. The fundamental particle in this context is a neutron (n), which has no charge and is a component of atomic nuclei.

### Step 3: Write the Reaction
When a neutron collides with Nitrogen-14, the reaction can be represented as follows:
\[ ^{14}_{7}N + ^{1}_{0}n \rightarrow ^{14}_{6}C + ^{1}_{1}H \]
Here, Nitrogen-14 (with 7 protons and 7 neutrons) captures a neutron, which results in the formation of Carbon-14 (with 6 protons and 8 neutrons) and a proton (which can be represented as Hydrogen-1).

### Step 4: Analyze the Products
From the reaction, we see that the nitrogen atom has transformed into a carbon atom, and a proton has been released. This indicates that the neutron has caused a nuclear reaction that changes the identity of the element.

### Step 5: Conclusion
Thus, the fundamental particle responsible for the transformation of Nitrogen-14 into Carbon-14 is the neutron.

### Final Answer
The answer to the question is that Carbon-14 is formed from Nitrogen-14 by the action of a neutron.
