## Producing and Balancing Nuclear Equations for Nuclear Fission and Fusion

**Producing and Balancing Nuclear Equations**

# Understanding Nuclear Equations

- Nuclear equations represent
**nuclear reactions**, displaying the**particles involved**in the reaction. - They show
**the balance of atomic and mass numbers**before and after the reactions.

# Fission Reaction

- In
**nuclear fission**, a heavy nucleus splits into two smaller ones, often releasing free neutrons and energy. - For instance, in the fission of Uranium-235, the nucleus absorbs a neutron and splits into Barium-141 and Krypton-92, releasing three additional neutrons.
**U^235 + n -> Ba^141 + Kr^92 + 3n**

- The atomic numbers (bottom numbers) on both sides of the equation add up (92 for Uranium + 0 for the neutron = 56 for Barium + 36 for Krypton), as do the mass numbers (top numbers).

# Fusion Reaction

- In
**nuclear fusion**, light atomic nuclei combine to form a heavier nucleus, with the release of energy. - It’s the reaction that powers the Sun, where hydrogen nuclei fuse to form helium:
**1H^2 + 1H^2 -> 2He^4 + energy**

- In this equation, both atomic and mass numbers are again balanced (1+1=2 for atomic numbers, 2+2=4 for mass numbers).

# Balancing Nuclear Equations

- To balance a nuclear equation:
- Make sure the
**sum of atomic numbers (proton numbers)**is the same on both sides of the equation. This is due to the conservation of charge. - Ensure the
**sum of mass numbers (protons + neutrons)**is also the same on both sides. This is because of the law of conservation of mass.

- Make sure the

# Importance of Balancing Equations

**Balanced nuclear equations**give a clear visual representation of what occurs during a nuclear reaction.- They show the
**conservation of mass and charge**. - These practises help with the understanding of both the theory and practical applications of nuclear physics.
