It is only the protons that matter in classifying the element. Sulfur has 16 protons (An atomic number of 16).
Sulphur.
18 neutrons.
Atomic number = Number of protons = 35 - 18 = 17.So the element is chlorine.
It is the Noble gas Argon.
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
Sulfur has 16 protons, 16 electrons and 16, 17, 18 or 20 neutrons ( the number of neutrons is different for each isotope).
Many isotopes have 18 neutrons.
A bunch of elements can have 18 neutrons because of isotopes in the world
35, 16, and another number. S=Sulfur off the periodic table.
neutrons = 40 - 18 = 22
18 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.
The most stable isotope of Argon has 22 neutrons (Ar40)
Chlorine maybe? It has 17 protons and a mass of 35, so 35-17= 18 neutrons.
34 - 16, the atomic number of sulfur [note correct spelling] or 18.
Yes. Atoms with a different number of neutrons are called isotopes of that atom, but a variation in the number of neutrons does not change what the atom is.
Argon has 18 protons, 18 electrons. The most stable isotope of argon (Ar-40) has 22 neutrons.
