A certain nucleus X has a mass number 14 and atomic number 6. The nucleus X changes to `""_(7)Y^(14)` after the loss of a particle.
Represent this change in the form of an equation.

Explanation

To represent the change of nucleus X to nucleus Y after the loss of a particle, we need to understand the details given in the question:

1. **Identify the nucleus X**:
- Mass number (A) = 14
- Atomic number (Z) = 6
- This means nucleus X can be represented as \( _6^{14}X \).

2. **Identify the nucleus Y**:
