Which part of an atom participates in the reaction shown below?


U235 + n → Xe134 + Sr100 + 2n

ANuclei
BProtons
CValence electrons
DInner shell electrons

Verified Answer :

the answer is nuclei

Answer: Option (A) is the correct answer.

Explanation:

A reaction in which nucleus of an atom and a subatomic particle like proton or neutron collide or when any two nuclei combine together then it results in the formation of a new nucleus that is different from its parent nuclei.

For example, \(^{235}U + n \rightarrow ^{134}Xe + ^{100}Sr + 2n\)

Here, nucleus of Uranium collides with a neutron resulting in formation of a Xenon and Strontium nucleus along with two neutrons.

Therefore, we can conclude that nuclei of an atom participates in the given  reaction.
