Question

When Uranium is bombarded with neutrons, it undergoes fission. The fission reaction can be written as :
${}_{92}{U}^{235}+{}_0{n}^1\to {}_{56}B{a}^{141}+{}_{36}K{r}^{92}+3x+Q$ (energy)
where three particles named $x$ are produced and energy $Q$ is released. What is the name of the particle $x$ ?

• A. electron
• B. $\alpha$-particle
• C. neutron
• D. neutrino

Answer 1

Answer: (C)

Nuclear fission equation
${}_{92}{U}^{235}{+}_0{n}^1{\to }_{56}B{a}^{141}{+}_{36}K{r}^{92}+3_0{n}^1+Q$ (energy)
Hence particle $x$ is neutron.
