A neutron strikes an atom of uranium-235 to start a fission reaction. A student expresses this situation as ga +235 U. Which statement describes why the expression is incorrect? (1 point)
• A neutron should be expressed as in, not In.
o The mass number for uranium-235 is in the wrong location.
• A neutron should be expressed as jH, not gn.
• The atomic number for uranium-235 is in the wrong location.
• A neutron should be expressed as in, not In.
o The mass number for uranium-235 is in the wrong location.
• A neutron should be expressed as jH, not gn.
• The atomic number for uranium-235 is in the wrong location.

The correct statement that describes why the expression "ga + 235 U" is incorrect is:
• A neutron should be expressed as n, not In.
In nuclear reactions, a neutron is represented by the letter "n." The notation for uranium-235 should properly reflect its atomic number (which is 92) and mass number (which is 235), typically written as \(_{92}^{235}\text{U}\) if using the isotope notation, but just using "235 U" without the atomic number is common in many contexts. The main error here is the incorrect representation of the neutron.
