The statement that describes why the expression is incorrect is:

A neutron should be expressed as 1/0n, not 0/1n.

The correct notation for a neutron is indeed \( ^{1}_{0}n \), where 1 is the mass number and 0 is the atomic number. The notation \( 0/1n \) is not standard and does not accurately represent a neutron.
