To determine the charge of each particle, let's analyze the number of protons and electrons:

Particle X
- Protons: 11
- Neutrons: 12
- Electrons: 10
Since the number of protons (11) is greater than the number of electrons (10), Particle X has a *positive charge*.

Particle Y
- Protons: 15
- Neutrons: 16
- Electrons: 15
The number of protons (15) equals the number of electrons (15), making Particle Y a *neutral atom*.

Particle Z
- Protons: 9
- Neutrons: 10
- Electrons: 10
Since the number of protons (9) is less than the number of electrons (10), Particle Z has a *negative charge*.

In summary:

- Particle X has a *positive charge*.
- Particle Y is a *neutral atom*.
- Particle Z has a *negative charge*.
