But that’s not the point of the periodic table. The periodic table is intended to represent how each element relates to each other in a format that is relatively simple to understand.

“The most stable one? Either an isotope is stable, or it isn’t”.

Radioactive elements? Not all isotopes are stable and not always is the most abundant isotope stable.

“It just says the atomic weight is 35.453, as a result of it being a mixture of 35 and 37”

Wrong. You fail chemistry. The atomic mass of CL 35 is 35.453 as a result of CL 35 having 17 protons and 18 neutrons.

See what I mean? You’re already confused as to what atomic mass means because of this bullshit change. I rest my case.

CL 35 the 35 means that it has 17 protons and 18 neutrons. Why isn’t this 35.000 instead of 35.453? Because the mass of the neutron is the combined mass of a proton plus an electron. That’s where you get the extra bit on.

Whether you can understand it or not, it shows how the elements relate to one another.

Um, yeah, those "aren't stable." As in, isotopes are stable or they AREN'T STABLE. I stand by what I wrote.

Nope, you're wrong. I have tried to correct you several times, but you have not only resisted every effort, but you have adopted such an attitude that I'm done with you. Scroll down to chlorine on this page. http://www.chemguide.co.uk/analysis/masspec/elements.html Or maybe this page: http://www.webelements.com/chlorine/isotopes.html Or just search for "Chlorine isotopic abundance."

And then apologize.

Until then, goodbye.

The format of your post is a little confusing. Are these your words? If so, you are incorrect. It is because it is a mixture of 35CL and 37CL and is a result of CL 35 having 17 protons and 18 neutrons CL 37 having 17 protons and ____ neutrons. I will let you fill in the blank.
