Question

which part of an atom participates in the reaction shown below? u^{235}+n→xe^{134}+sr^{100}+2n a nuclei b protons c valence electrons d inner shell electrons

Explanation:

The given reaction is a nuclear fission reaction where a uranium - 235 nucleus absorbs a neutron and splits into xenon - 134 and strontium - 100 nuclei along with more neutrons. In nuclear reactions, it is the nuclei of atoms that participate. Protons are part of the nucleus but the whole nucleus is involved in fission. Valence electrons and inner - shell electrons are involved in chemical reactions, not nuclear reactions.

Answer:

A. Nuclei
