?

I have NEVER bought jewelry - ever. But I recently entered a relationship that is becoming somewhat serious and would like to get my girl some jewelry for Christmas, and I know that she likes James Avery charms from her parents so I thought I might get her a pendant necklace from the same place.

My question is, do you have to buy a chain for the pendant or do the pendants come with one? I could not find any info on their website regarding this, but the pictures just show a pendant without a chain..

Thanks!

I am considering buying an Indochino suit and have done a lot of research, so I am only interested in what people who have bought their suits have to say.

I have found a lot of good AND bad stuff about the suits. The only reason I am worried is I have somewhat of an odd build rather than a usual/average form due to my broad shoulders, and I am worried that because of the abnormal shape I will end up falling into the "bad" category of experiences with the company.

I really want a made to measure or bespoke suit, so this seems like the best option for my budget it seems (bespoke suits are obscenely expensive and I live in Oklahoma, where there is little bespoke tailors). So if you have any other suggestions that would be nice. Thanks!

I started to put this in Physics, but the process seems to involved more with chemistry, as it pertains to the changing of materials.

What I would like to know is how exactly radioactive decay results in different, more stable elements. I understand the alpha and beta decay properties, that it is emitting energy, that the element undergoes several changes into other elements becoming more and more stable, etc. What I am wondering is how exactly does that result in a wholly different kind of atom.

What I mean is, I thought elements were made up of a specific kind of atom, i.e. carbon is made up of uniquely alike carbon atoms, aluminum made of all aluminum atoms, etc. So then, how does the entire sample of atoms convert into an entirely different element? I mean, is uranium not made up of uniquely alike uranium atoms?

Or is it that all atoms are inherently alike, and that their specific combination of subatomic particles (proton, neutron, and electron combinations) results in producing atoms that are similar and thus compose together to produce a certain element? If this is the case, then I can understand how ionization and decay strips electrons over time, eventually changing that unique combination of subatomic particles until it eventually becomes stable lead.

However, I was under the assumption that all atoms are unique to one of the many elements and always remained that kind of atom (for example, a hydrogen atom always remaining a hydrogen atom), which would mean that a uranium atom could never become a lead atom, regardless of radioactive decay. It doesn't really make sense to me that the atoms that compose an element could just entirely change into atoms that combine another element. For example, you don't see mercury becoming boron, or neon turning into gold. For instance, I thought this is the reason the fictional process of alchemy (turning another metal into gold) was impossible.
