1 answer

The correct statement that describes why the expression is incorrect is:

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

In nuclear notation, the neutron is represented by \( ^1_0n \) (with the mass number of 1 and atomic number of 0). The expression \( 0/1n \) is incorrect because it places the mass number in the wrong location relative to the atomic number.
