Iron-59 has 33 neutrons because its atomic number is 26, which means it has 26 protons. The mass number of iron-59 is 59, which is the sum of protons and neutrons in the nucleus. To find the number of neutrons, you subtract the number of protons from the mass number: 59 (mass number) - 26 (protons) = 33 neutrons.
The only naturally occurring isotope of As (atomnumber 33) is As-75 (76 and 77 have decay half-time of several houres)This As-75 has 33 protons, 33 electrons and (75-33 =) 42 neutrons
33 neutrons
The mass number for an atom is the sum of its protons and neutrons. Given that cobalt has 27 protons, an atom with 33 neutrons would have a mass number of 60 (27 protons + 33 neutrons).
There are about 33 isotopes of arsenic. Only one of them is stable, and that's 75 As 33. All the other isotopes are synthetic.
The only element which has a reasonably abundant isotope with mass number 33 is sulphur and that has 17 neutrons.

The isotope with 16 protons and 17 neutrons is oxygen-33.
Ah, what a happy little question! Phosphorus-33 has 16 neutrons. Just imagine those neutrons snuggled up with the protons in the nucleus, creating a lovely balance in the atom. Remember, every element has its own unique number of protons and neutrons that make it special.
Arsenic is a non metal element. There are 33 electrons in a single atom.
There are about 33 isotopes of arsenic. Only one of them is stable, and that's 75 As 33. All the other isotopes are synthetic.

Since cobalt has an atomic number of 27, any isotope of it contains 27 protons and 27 electrons per atom. The isotope with mass number 60 contains (60 - 27) or 33 neutrons per atom.

Number of nucleons = number of protons + neutrons = 16 + 17 = 33 The mass number is thus 33 and the atom is denoted sulfur-33 or 33S.
