Question

A neutron strikes an atom of uranium-235 to start a fission reaction. A student expresses this situation as 01n+235 92U
. Which statement describes why the expression is incorrect?(1 point)
Responses

A neutron should be expressed as 11H
, not 01n
.
A neutron should be expressed as 1 to the 1th power cap h, not 1 to the 0 power n.

A neutron should be expressed as 10n
, not 01n
.
A neutron should be expressed as 0 to the 1th power n, not 1 to the 0 power n.

The mass number for uranium-235 is in the wrong location.
The mass number for uranium-235 is in the wrong location.

The atomic number for uranium-235 is in the wrong location.

Answer 1

The correct response is:

**A neutron should be expressed as \( ^1_0n \), not \( ^0_1n \).**

This highlights that the notation for the neutron is incorrect in the expression provided. The correct notation for a neutron indicates that it has a mass number of 1 and an atomic number of 0, represented as \( ^1_0n \).
