The only element which has a reasonably abundant isotope with mass number 33 is sulphur and that has 17 neutrons.
17P 15
The number of protons is the atomic mass minus the number of neutrons; in this instance 32 - 17 or 15. An atomic number of 15 corresponds to the element phosphorus; therefore, the isotope is P-32.
8 protons and 9 neutrons (total is the atomic mass number 17). In a neutral atom, 8 electrons. Oxygen-17 is the rarest of the three stable natural isotopes. Most oxygen is oxygen-16 with 8 neutrons.
The isotope Chlorine-37 (or denoted as 37Cl) has 20 neutrons per atom. 37 is the mass number (sum of number of neutrons and protons per atom) and we know that the atomic number for Cl irregardless of whichever isotope is 17, which means all Cl atoms have 17 protons. Therefore the number of neutrons for Chlorine-37 is 37 - 17 = 20.

Chlorine has 17 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a chlorine isotope = Mass number - 17
The number of protons is the atomic mass minus the number of neutrons; in this instance 32 - 17 or 15. An atomic number of 15 corresponds to the element phosphorus; therefore, the isotope is P-32.
atomic number = 17 mass number = 37
8 protons and 9 neutrons (total is the atomic mass number 17). In a neutral atom, 8 electrons. Oxygen-17 is the rarest of the three stable natural isotopes. Most oxygen is oxygen-16 with 8 neutrons.
Chlorine 35 is a natural isotope of chlorine (75,77 % as mass).
17 plus 17 equals 34. However, Chlorine-34 does not exist; the stable isotopes are Chlorine-35 and Chlorine-37.
Cl-35 isotope has 18 neutrons Cl-37 isotope has 20 neutrons
The isotope Chlorine-37 (or denoted as 37Cl) has 20 neutrons per atom. 37 is the mass number (sum of number of neutrons and protons per atom) and we know that the atomic number for Cl irregardless of whichever isotope is 17, which means all Cl atoms have 17 protons. Therefore the number of neutrons for Chlorine-37 is 37 - 17 = 20.
Chlorine atoms always have 17 protons. The number of neutrons equals the mass number of the isotope named minus the number of protons: in this instance, 35 - 17 or 18.
