The nuclear equation is incomplete. superscript 239 subscript 94 baseline p u + superscript 1 subscript 0 baseline n yields superscript 100 subscript 40 baseline z r + blank + 2 superscript 1 subscript 0 baseline n what particle completes the equation?

The particle which completes the given equation  is :

Explanation:

The given reaction is of a fission reaction:

Total mass on the reactant side is equal to the total mass on the product side:

239 + 1 = 100 +A+ 2

A = 138

Sum of atomic numbers on the reactant side is equal to the sum of atomic number on the product side:

94 + 1(0) = 40 + Z + 2(0)

Z = 54

So atomic number 54 id of Xenon.

The particle which completes the given equation  is :

the correct choice is a .
