B = 146
C = 56
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
Reaction(Fission reaction ) :
[tex]\tt ^{239}_{94}Pu+^1_0n\rightarrow ^B_CBa+^{91}_{38}Sr+3^1_0n[/tex]
mass number :
[tex]\tt 239+1=B+91+3.1\\\\240=B+94\\\\B=146[/tex]
atomic number :
[tex]\tt 94+0=C+38+3.0\\\\94=C+38\\\\C=56[/tex]
