Answer:

d

Explanation:

Answer: B. Mass number minus atomic number

Explanation: The atomic # is equal to the # of protons. The mass number is the total mass of neutrons & protons. You subtract the protons (atomic number) from the mass of the atom, the formula would be as shown:

Mass - Protons = Neutrons

An example is shown below

Element: Tin

Name shown on periodic table: Sn

Atomic #: 50

Mass # 118.711

118.711 - 50 = 68.711    <--- answer

Mass^     ^Protons/ Atomic #
