Only one isotope has a given number of protons andneutrons. In this case it is Argon-40
Argon (Ar)....Argon has 18 protons as shown by the periodic table...And 18+22=40, which is the atomic weight of Argon
The element is sulphur and the isotope is 16S35.

Cl-37 : 17 protons , 20 neutrons , 17 electrons Compare with Cl-35 ; 17 protons , 18 neutrons, 17 electrons. These are two different and common isotopes of chlorine. Remember 'Different isotopes have a different number of neutrons'. Chemically they react the same.
A phosphorus atoms has 15 protons and will form an ion with 18 electrons. Phosphorus-31 is one of the isotopes.
18 protons 18 electrons 22 neutrons
Oxygen-17 and oxygen-18 are isotopes of oxygen, which are different atoms of the same element with the same number of protons but different number of neutrons. Both of them have 8 protons in their nucleus and 8 electrons but oxygen-17 has 9 neutrons which oxygen-18 has 10 neutrons.
Hydrochloric acid consists of one Hydrogen and one Chlorine atom - HCL. Hydrogen has only one proton, Chlorine has 17 Protons, 18 neutrons so HCL has 1 + 17 = 18 protons, 0 + 18 neutrons = 18 neutrons, HCL has 18 protons and 18 neutrons.
An oxygen always has 8 protons and normally has 8 neutrons, but a very small minority of oxygen atoms are isotopes of oxygen-17 or oxygen-18 which contain 9 or 10 neutrons respectively.
The atomic number of oxygen is 8. So it has 8 protons. And O-18 isotope has 10 neutrons.
Every chlorine atom has 17 protons; 17 is the atomic number of chlorine. However, chlorine has two isotopes that are stable against radioactive decay. These have mass numbers of 35 and 37, which have 18 and 20 neutrons respectively.

Cl-37 : 17 protons , 20 neutrons , 17 electrons Compare with Cl-35 ; 17 protons , 18 neutrons, 17 electrons. These are two different and common isotopes of chlorine. Remember 'Different isotopes have a different number of neutrons'. Chemically they react the same.
Most elements have isotopes---atoms that have the same number of protons (and hence they are still that element) but different numbers of neutrons. For instance, sulfur found in nature has four stable isotopes: S-32 16 protons 16 neutrons S-33 16 protons 17 neutrons S-34 16 protons 18 neutrons S-36 16 protons 20 neutrons Each of these isotopes has a different mass, but all are sulfur because they have 16 protons.
Number of Protons = Number of electrons = 17.The number of neutrons depends on the isotope. Cl-35 and Cl-37 isotopes have 18 and 20 isotopes respectively.
There are 16 protons, 16 neutrons and 16 electrons in a Sulfur atom. *note it's atomic number- this is the number of protons in an atom of an element. There must be the same number of electrons to balance the charge. The atomic weight minus the number of protons gives you the number of neutrons
A phosphorus atoms has 15 protons and will form an ion with 18 electrons. Phosphorus-31 is one of the isotopes.
18 protons 18 electrons 22 neutrons
There are several. However, Chlorine is one. Chlorine-35 has 17 protons, 18 neutrons and 17 electrons in its isotopic atom. However, Chlorine-37 has 17 protons, 20 neutrons and 17 electrons in its isotopic atom.
These are both isotopes of oxygen, meaning that they have different numbers of neutrons but the same number of protons.
