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