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
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.
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.

"Felix" is the English name that comes from "iron59." Fe represents the symbol for iron while LIX serves as the number "59" in Roman numerals. The pronunciation will be "FEE-liks" in the Mid-Atlantic pronunciation patterns of United States English.
