Which answer choice represents a balanced alpha emission nuclear equation? Superscript 52 subscript 26 upper F e right arrow superscript 52 subscript 25 upper M n plus superscript o subscript plus 1 e. Superscript 235 subscript 92 upper U right arrow superscript 239 subscript 94 upper P u s plus superscript 4 subscript 2 upper H e. Superscript 189 subscript 83 upper Bi right arrow superscript 185 subscript 81 upper T l plus superscript 4 subscript 2 H e. Superscript 14 subscript 6 upper C right arrow superscript 14 subscript 7 upper N plus superscript 0 subscript negative 1 e.

The answer choice that represents a balanced alpha emission is as follows: superscript 189 subscript 83 upper Bi right arrow superscript 185 subscript 81 upper Tl plus superscript 4 subscript 2 He.

What is a nuclear reaction?

A nuclear reaction is a reaction such as the fission of an atomic nucleus or the fusion of one or more atomic nuclei and/or subatomic particles in which the number of protons and/or neutrons in a nucleus changes.

A nuclear reaction involves a change in the number of atoms, hence, is said to be balanced when the number of atoms in the reactant side equates that of the product side.

Therefore, the answer choice that represents a balanced alpha emission is as follows: superscript 189 subscript 83 upper Bi right arrow superscript 185 subscript 81 upper Tl plus superscript 4 subscript 2 He.
