The number of neutrons in an isotope of argon that has a mass number of 40 and an atomic number of 18?
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
How many protons neutrons and electrons in 40 Ar?
18 protons 18 electrons 22 neutrons
What element has 18 protons?
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
What is the mass number of an atom with 18 protons 22 neutrons and 18 electrons?
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
What isotopes contain 18 protons and 22 neutrons?
Only one isotope has a given number of protons andneutrons. In this case it is Argon-40
