The only element which has a reasonably abundant isotope with mass number 33 is sulphur and that has 17 neutrons.
The mass number of an atom is the sum of its protons and neutrons. In this case, the atom has 27 protons and 33 neutrons, so the mass number would be 27 + 33 = 60.
Arsenic atoms typically consist of 33 protons, 33 electrons, and varying numbers of neutrons depending on the isotope. Each subatomic particle has its own specific role in determining the properties and behavior of the arsenic atom.
One can ignore the scant contribution of electrons to atomic mass. Simply add the number of protons and neutrons to obtain 53. Please see the link.
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
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.

The proton number for an isotope of iron with 59 mass number would be 26, as iron has 26 protons in its nucleus. Since the mass number is 59 and the proton number is 26, the number of neutrons would be 33 (59 - 26).

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.
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.
An isotope with 35 neutrons and a charge of 2+ means it has 33 electrons (atomic number - charge). The atomic number can be calculated by subtracting the number of neutrons (mass number) from the relative atomic mass, so in this case, the atomic number is 30 (65 - 35).
The more stable polonium atoms have 125 neutrons. As with other elements, polonium atoms can have varying numbers of isotopes (variants with different number of neutrons).Polonium has 33 isotopes ranging from 104 to 136 neutrons.
The 34 protons means that this is the element that has an atomic number of 34, which is selenium. The mass number for the isotope given is 67, which is the sum of the protons and neutrons. Mass number is not the same as atomic mass. Atomic mass is the total mass of the protons, neutrons, and electrons in an atom.
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).
