Only one isotope has a given number of protons andneutrons. In this case it is Argon-40
Oxigen has 8 protons; natural isotopes have 8, 9 an 10 neutrons.
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.
18 protons 18 electrons 22 neutrons
Oxygen with 8 protons and 8 neutrons is the stable isotope oxygen-16. The rare form with two extra neutrons is the isotope oxygen-18. Both isotopes have the same number of protons (8) but differ in the number of neutrons, resulting in different atomic masses.
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.
Oxigen has 8 protons; natural isotopes have 8, 9 an 10 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.

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.

An isotope of oxygen with atomic number 8 could have various numbers of neutrons, leading to different mass numbers. Isotopes such as oxygen-16 (8 protons and 8 neutrons), oxygen-17 (8 protons and 9 neutrons), and oxygen-18 (8 protons and 10 neutrons) are examples of isotopes of oxygen that exist.
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.
No, oxygen-17 and oxygen-18 are different isotopes of oxygen. They differ in the number of neutrons each atom contains. Oxygen-17 has 8 protons and 9 neutrons while oxygen-18 has 8 protons and 10 neutrons.
