Question

Product of the following nuclear reaction is :

${}_{98}^{250}Cf{+}_5^{11}B⟶?+4_0^{1}n$

• A. ${}_{103}^{257}Lr$
• B. ${}_{105}^{255}Lr$
• C. ${}_{104}^{256}Lr$
• D. None of these

Answer 1

The correct option is A ${}_{103}^{257}Lr$

The balanced reaction is as follows:

${}_{98}^{250}Cf{+}_5^{11}B{\to }_{103}^{257}Lr+4_0^{1}n$

As in this case sum of both atomic and mass number is conserved in product and reactant side
