I think you ought to review my posts with Dimmerswitch's post in mind. I referenced the sun, and so did he, but I think his rhetoric is better.
The fraction of atoms in the sun as an expression of all atoms in our solar system is a fairly convincing majority, and I'm willing to accept that as representative of most star systems in the universe provisionally.
This implies that most atoms in star systems in the universe we can observe are inside what are essentially fusion reactors. I won't press the counter position, but right now, it seems more convincing to me that most atoms are actually in flux rather than stable, especially as you've done nothing to advance your thesis!
By the by, asking you to cite sources for your thesis is neither arbitrary nor stupid. It's clarifying and informative, which is why most scientific papers are riddled with references to related studies, as boring and unhelpful as that might be to lay readers.
Asking for clarification, precision, references and proof - this is how a scientist talks about science topics. I thought you would appreciate it.
Carry on.
This really, really reminds me of my daughter (4 years old at the moment) who, when I tell her that it is time to go to bed, yells at me "But I can't go to bed. Water is wet!!"
Not at all, Malor. I have already stipulated that I agree that molecular reactions would not affect atoms. I don't see what's so amazing about it, though, since those reactions are called "molecular" and not "atomic."
You did not specify this in your initial statement, in which you also included molecules. Removing movelcules is changing the statement, not refining it.
None of this proves that atoms "stay the way they are, basically forever," since that would assume that most reactions that happen to most atoms are molecular in nature.
Note also that my very first post objecting to your statement mentions fusion reactions in stars. If you wanted to simply say that atoms do not change in most chemical reactions, you might have restated your position as such then and there, and I would have agreed with that generalization.
As it is, your current statement is so far removed from the first one that I despair of any proof along those lines.

Did you get the questions that the Department of Redundancy Departments was questioning you about?
Wow, this thread is definitely bringing out the best in everyone!

I don't want to play junior moderator here, but I wonder if this thread would be better directed into PM territory.
I was not feigning ignorance, Malor, and I didn't know that that was what you meant. Frankly, it's astoundingly bad to say "Atoms and molecules" when you mean "really just atoms," and "physics" when you mean "chemistry."
I still do not think that the initial statement was anywhere close to "mostly right," and it's not a personal attack to ask you to present the science behind your assertions. It's a challenge and a call to discussion, but not a personal attack. If I called your behavior unattractive and said that you were a liar - that would be a personal attack.
Paleocon:
The way it's going, probably. I was hoping for a science discussion of some sort, something interesting.
Along those lines, I was hoping to talk about the time scale, too. Malor implies that the duration of the Earth's skin being separate from the fusion furnace of the sun "the next thing to forever," but I'm surmising that it must be something finite - maybe like 5 billion years - before the sun goes red giant on us and engulfs the Earth. Still longer than anything that would have any pragmatic impact.
I was hoping to talk about atoms, molecules, time, and various reactions.
Generally, I've always interpreted it as how Malor describes it. An atom of an element is just that. Combine it, seperate it, making pretty molecules to infinity and beyond.
What about the radioactive elements. They have half-life, which in a simple way equates to kinda wearing out.. doesnt it?
Maybe?
I dunno anything. Just trying to find a point where both of you may be correct based on certain scenarios, so you can hug and play games together again.
To hopefully answer a few questions:
1) Nuclear fusion occurs only in the sun's core.
2) The core accounts for about 40% of the sun's mass and about 10% of its volume.

My totally general and basic understanding was that all atoms had half-lives, but the "radioactive" atoms have half-lives many orders of magnitude less than stable atoms . I was under the impression that eventually, many billions of years from now, all matter will be in a cloud of disperse iron atoms.

Well, Malor references a pretty decent meaning of the word "wear." Radioactive atoms don't change because of use, and certainly not because of friction. They change because they're unstable. The best word to describe this process is, I think, the word that's actually used to refer to it - decay.

It's not that at all. I wouldn't consider radioactive decay as "wear" anymore than I would consider the disappearance of my dinner due to my "using it" as "wear." It's the uncertainty that made me focus on later clarifying statement "will stay as they are," in Malor's initial thesis.

Typically stable atoms have half lives so long that they can't be estimated, it's not just that the half life is billions of years. And some nuclides are understood to be energetically stable to all types of decay, so attempting to calculate a half life is an actually meaningless exercise.
Anyhoo... Sure, the majority of atoms in the universe seem to be Hydrogen and Helium and the vast majority of them are inside stars, with some being transmuted by fusion into other atoms but conceptualising that process in terms of "wear" fundamentally misunderstands what atoms are. There is nothing about an atom that can become worn, certainly not in the sense of macroscopic objects that we interact with. That said I did understand what Malor was originally getting at so I don't really understand what this little to do is about.
I was only able to skim the whole thread but the one thing that I noticed that was missing were the parameters under which the statement, "atoms don't exhibit wear" would be true. Also, as many have said, what would constitute wearing out an atom?
Personally, I would have started with an adiabatic system in a vacuum. With no energy going in or out and no other atoms for a test atom to interact with, then you'd at least establish a common starting point for proper discourse. Then you could introduce other conditions like energy in various wavelengths, bombarding the system with high speed electrons, subparticles, protons, neutrons, etc. In the end, you would at least find the conditions under which the atom exhibits not 'wearing out' and the conditions where it exhibits 'wear out'.
I could be wrong, but I think that a concept that would be pertinent to this discussion would be entropy. I seem to remember hearing that as the entropy in our universe tends toward infinity all atoms will be eventually break apart into their constituents thus leaving behind a homogenous mixture of protons, neutrons and electrons or something like that.
In essence, the argument thus far has been based upon miscommunication and a distinct lack of scientific method (I am not to well versed in the scientific method though). If this is truly a discussion, then there is no need for one individual to be correct at the expense of the other being wrong.
On a side note, since particles exist as a probability waves, as modeled in Quantum Physics, I'd be interested to know if making an observation and thus collapsing the probability wave over and over again has any effect on an atom. I am only a neophyte when it comes to Quantum Physics, but I'd be interested to know if an atom that is measured time and time again is any different than an atom that is measured less.
Ok, so the entire argument was a moot point because Malor and LarryC were each using a semantically different meaning of "wear out" in regards to the atomic lifespan, right? Because otherwise this thread is so far over my head that I just don't see it.

I can speak for myself, Malor, and I definitely did not do so. Obviously, were I inclined, I would have confused "NOT wear out" as "immutable," not the other way around.
The thing is, Malor, you were using "wear" as a concept referring to atoms, when the concept of "wear" would simply not be applicable. Friction does not degrade atoms, unsurprisingly; and chemical reactions do not do so either, also unsurprisingly.

As far as I understand it, Malor was using "wear" to refer to the specific observation that atomic nature does not change when atoms engage in chemical reactions, whereas I was under the impression that it related to atomic change in the general. I find the use unintuitive and strange, myself.

That is perfectly true. I had already conceded that Malor is using valid scientific theory and confirm-able observation when he says that atoms do not exhibit change in molecular reactions.
What is occurring is not, I would say, scientific method proper, since that is a description of experimental methodology. It's something more along the lines of peer review. Malor is forwarding a thesis, and I am pointing out its weaknesses. That said, there hasn't been much of that going on, either, admittedly.
