Further explanation
There are two types of nuclear reactions
Fission reaction is the splitting of an atomic nucleus by firing a particle
Fusion reaction is a combination of two atomic nuclei
There are several particles involved in atomic nuclei reactions:
- alpha α particles ₂He⁴
- beta β ₋₁e⁰ particles
- gamma particles γ
- positron particles ₁e⁰
- neutron particles ₀n¹
In a nuclear reaction, it is always found that the atomic number (Z) and mass number (A) are the same either before or after the reaction
