The correct option for the statement, which describes how to find the number of neutrons is "D: Subtract the atomic number from the mass number."

The atomic number of an element is defined as the number of electrons orbiting the nucleus of the atom of that element. It also represents the number of protons inside the nucleus of the atom.

The mass number is defined as the sum of the number of protons and the number of neutrons inside the nucleus of the atom of an element.

Hence, when we subtract the atomic number from the mass number, we get the number of neutrons, as follows:

=> Mass Number - Atomic Number

=> (No. of Neutrons + No. of Protons) - No. of Protons

=> No. of Neutrons

Therefore,

Mass Number - Atomic Number = No. of Neutrons
