The correct response to why the expression \( ^{01}n + \, ^{235}_{92}U \) is incorrect is:
**A neutron should be expressed as \( ^{1}_{0}n \), not \( ^{0}_{1}n \).**
In nuclear notation, the mass number (number of nucleons) is written as the superscript and the atomic number (number of protons) is written as the subscript. For a neutron, the mass number is 1 and the atomic number is 0, hence it should be written as \( ^{1}_{0}n \).
**A neutron should be expressed as \( ^{1}_{0}n \), not \( ^{0}_{1}n \).**
