It is the Noble gas Argon.
Argon
argon is element 18, and so has 18 protons. argon 40 has a mass of 40, so subtracting 18 protons gives you 22. Thus, there are 22 neutrons
18 protons 18 electrons 22 neutrons
Argon has 18 protons, 22 neutrons, and 18 electrons.
The element argon has 22 neutrons. It has 18 protons and 18 electrons, giving it an atomic number of 18. The number of neutrons is calculated by subtracting the atomic number from the atomic mass, which is 40 for argon (obtained by rounding the atomic weight to the nearest whole number).
if you were to count the individual weight of all the protons neutrons and electrons you will get 40. however this is not the case when they are joined together due to something call the strong neuclear force which causes the atom to weigh 39.9

Titanium is the element having 22 protons and 21 neutrons. Its symbol is Ti.
18 protons and 18, 20 or 22 neutrons.
Argon has 18 protons, 18 electrons. The most stable isotope of argon (Ar-40) has 22 neutrons.
18 protons and 22 neutrons in the most commonly occurring isotope argon-40. In argon-36 there are 18 neutrons but this isotope is only present in nature at 0.34%
18 protons and electrons and 22 neutrons.
The element that has 18 neutrons is ARGON... Wow, why didn't look in a periodic table? Is easier ask here??? Actually, 18 is argon's atomic number, and it also has 18 protons and electrons.. but it has 22 neutrons. The number of neutrons = mass number - number of protons. Soo, the answer is Chlorine, 17 protons, 17 electrons and 18 neutrons

The element with 22 protons is titanium (Ti). The sum of protons and neutrons determines the isotope, so with 26 neutrons, the isotope is titanium-48 (22 protons + 26 neutrons = Ti-48).
Only one isotope has a given number of protons andneutrons. In this case it is Argon-40
Argon has 18 protons, 22 neutrons, and 18 electrons.
