When Uranium is bombarded with neutrons, it undergoes fission. The fission reaction can be written as : _ 92 U^ 235 + _0 n^1 arrow _ 56 Ba^ 141 + _ 36 Kr^ 92 +3 x+Q( energy) where three particles named x are produced

Correct answer: C. neutron Nuclear fission equation aligned _ 92 U^ 135 + _0 n^1 & _ 56 Ba^ 141 + _ 36 Kr^ 92 & +3 _0 n^1+Q( energy ) aligned Hence particle x is neutron.

When Uranium is bombarded with neutrons, it undergoes fission. The fission reaction can be written as :

{ }_{92} \mathrm{U}^{235}+{ }_0 n^1 \rightarrow{ }_{56} \mathrm{Ba}^{141}+{ }_{36} \mathrm{Kr}^{92}+3 x+\mathrm{Q}(

energy) where three particles named

x

are produced and energy

\mathrm{Q}

is released. What is the name of the particle

x

Options

Aelectron
B $\alpha$ -particle
Cneutron
Dneutrino

Correct answer

C. neutron

Step-by-step solution

Nuclear fission equation

\begin{aligned} { }_{92} \mathrm{U}^{135}+{ }_0 \mathrm{n}^1 \longrightarrow & { }_{56} \mathrm{Ba}^{141}+{ }_{36} \mathrm{Kr}^{92} \\ & +3{ }_0 \mathrm{n}^1+\mathrm{Q}(\text{ energy }) \end{aligned}

Hence particle

\mathrm{x}

is neutron.
