### Table: Characteristics of Atomic Nuclei

This table presents the mass, charge, and mass-to-charge ratio for various atomic nuclei, providing crucial information for understanding nuclear properties and reactions.

| Nucleus    | Mass, \( m \) (kg) | Charge, \( q \) (C) | Mass/Charge, \( m/q \) (kg/C) |
|------------|---------------------|----------------------|-------------------------------|
| Hydrogen   | \( 1.67 \times 10^{-27} \) | \( 1.60 \times 10^{-19} \) | \( 1.04 \times 10^{-8} \)   |
| Deuterium  | \( 3.35 \times 10^{-27} \) | \( 1.60 \times 10^{-19} \) | \( 2.09 \times 10^{-8} \)   |
| Tritium    | \( 5.01 \times 10^{-27} \) | \( 1.60 \times 10^{-19} \) | \( 3.13 \times 10^{-8} \)   |
| Helium-3   | \( 5.01 \times 10^{-27} \) | \( 3.20 \times 10^{-19} \) | \( 1.57 \times 10^{-8} \)   |

#### Explanation:

- **Nucleus**: Refers to the type of atomic nucleus considered.
- **Mass, \( m \)**: The mass of the nucleus expressed in kilograms.
- **Charge, \( q \)**: The electric charge of the nucleus expressed in coulombs.
- **Mass/Charge, \( m/q \)**: Represents the ratio of mass to charge, giving an indication of how mass is balanced by electric charge, which is significant for understanding behavior in magnetic and electric fields. 

The table highlights differences in properties between isotopes and elements, critical for applications in nuclear physics and chemistry.
