Answer :
Answer:
The missing particle is [tex]_{103}^{259}\textrm{Lr}[/tex].
Explanation:
In a nuclear reaction, the total mass and total atomic number remains the same.
For the given fission reaction:
[tex]^{252}_{98}\textrm{Cf}+^{10}_{5}\textrm{B}\rightarrow ^A_Z\textrm{X}+3^1_0\textrm{n}[/tex]
To calculate A:
Total mass on reactant side = total mass on product side
252 +10 = A+ 3
A = 259
To calculate Z:
Total atomic number on reactant side = total atomic number on product side
98 +5 = Z + 0
Z = 103
Hence, the isotopic symbol of unknown element is [tex]_{103}^{259}\textrm{Lr}[/tex]
