The isotope 35Cl has 18 neutrons.
The isotope 37Cl has 20 neutrons.
There are two fairly common isotopes for chlorine. One of them has 18 neutrons, the other has 20.
Chlorine has 17 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a chlorine isotope = Mass number - 17
Neutrons.
As a matter of fact, there are 18 neutrons in the chlorine atom.
The number of protons in Chlorine is relative to its atomic number of 17. The amount of protons will not change, or will become a different element. The 37 refers to the amount of nucleons in the element. The total nucleons is calculated by adding the amount of protons and neutrons, so if we know there are 17 protons, 37-17= 20 neutrons. There are 17 protons and 20 neutrons in Cl-37.
The "37" in the question refers to the mass number, the total number of protons plus neutrons. We are trying to figure out how many nuetrons there are, but one thing we absolutely do know is the number of protons. All atoms of the same element contain the same number of protons, which is also the same as the atomic number. So if you have a periodic table, you would see that chlorine's atomic number is 17. Then all we need to do is a little subtraction (37-17) to find the number of neutrons, 20.
The number of neutrons is different for each isotope. Chlorine-35 has eighteen neutrons. Chlorine-36 has nineteen neutrons. Chlorine-37 has twenty neutrons. ....... etc.
A chlorine atoms is always a molecule of chlorine, irrespective of the number of neutrons it may have.
Chlorine has 17 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a chlorine isotope = Mass number - 17
Neutrons.
Presumably you mean how many neutrons? Chlorine has various isotopes, each having a different number of neutrons - take the mass of the isotope, subtract the atomic number (17), and the answer is the number of neutrons.
The number of neutrons in chlorine is 18 (no of neutrons=atomic mass-no of protons=35-17=18)
18.5 neutrons Neutrons can not be a fraction. Must be a whole number. Chlorine has 18 neutrons
The number of neutrons in chlorine is 18 (no of neutrons=atomic mass-no of protons=35-17=18)
It has 18 neutrons. Its really simple, 35 is the mass number(A) i.e., the total number of neutrons and protons. We know atomic number(Z) of chlorine is 17. This is the number of protons. So A-Z will give us number of neutrons.
Chlorine exist as two isotopes(same number of electrons and protons but different number of neutrons), although there are traces of one more but we're not to sure. ~70% of Chlorine is Chlorine-35 which contains 17 electrons and 18 neutrons ~30% of Chlorine is Chlorine-37 which contains 17 electrons and 20 neutrons and ≤1% of Chlorine-36........
The isotope Chlorine-37 (or denoted as 37Cl) has 20 neutrons per atom. 37 is the mass number (sum of number of neutrons and protons per atom) and we know that the atomic number for Cl irregardless of whichever isotope is 17, which means all Cl atoms have 17 protons. Therefore the number of neutrons for Chlorine-37 is 37 - 17 = 20.
Mass number = No. of protons + No. of neutrons = 19 + 20 = 39
