Answer:

18 neutrons

Explanation:

  • The atomic number of sulfur is 16.
  • Atomic number indicates the number of protons in the nucleus of an atom.
  • Neutrons are found in the nucleus of an atom together with the protons and account for the difference in the mass number among isotopes of an element.
  • The sum of neutrons and protons gives the atomic mass number of an element.
  • Therefore; given the mass number and the atomic number(number of protons) we can calculate the number of neutrons.

Number of protons = 16

Mass number = 34

Number of neutrons = mass of number - number of protons

                                   = 34 - 16

                                  = 18 neutrons
