Which equation represents a fission reaction?
a. 14/7 n + 1/1 h --> 15/8o
b. 235/92 u + 1/0 n --> 94/37rb + 2 1/0 n
c. 9/4 be + 4/2 he --> 12/6 c + 1/0 n
d. 239/93 np --> 239/94 pu + 0/-1 e

The correct option is B.

Nuclear fission is a type of reaction in which the nucleus of an heavy radioactive element emits charged particles and break down into smaller nuclei. Nuclear fission involves the splitting of the nucleus of an element into smaller nuclei. The reaction can occur spontaneously or it can be made to occur by bombarding the radioactive element with high energy neutrons. The process of nuclear fission is used in America to generate electricity.
