I would give you the answer but to find it:
Take the atomic number (the one ontop) and subtract it from the Atomic Mass number (the one on the bottom) -rounding is involved (5 & up round up, 4 & down round down!)
Hope this helps.
18 neutrons.
There should be 17, since the atomic number is how many protons (of which there are the same amount of neutrons). However, if it is an unstable isotope, it would have more neutrons.
Neutrons.
Yes, the main isotope of chlorine has 17 protons and 18 neutrons.
19
The number of neutrons in chlorine is 18 (no of neutrons=atomic mass-no of protons=35-17=18)
The number of neutrons in chlorine is 18 (no of neutrons=atomic mass-no of protons=35-17=18)
It depends on which isotope of chlorine you're interested in.
the average amount of neutrons in chlorine is 18, but there could be more or less with the different isotopes
18
30 or 32 neutrons, because chlorine has two isotopes.
20
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.
A chlorine atoms is always a molecule of chlorine, irrespective of the number of neutrons it may have.
Because chlorine has two natural isotopes (and isotopes have different number of neutrons) the total number of neutrons is 30 and 32.
No. Sorry.
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.
