Question for who ever knows: How can a person tell how many isotopes each element has? Is there a way to tell by looking at the periodic table?
The CRC handbook lists the weights and half-lifes of known isotopes.
I’m not sure I’m ready for that stuff yet. But let me ask you the most basic question I can think of: does every atomic configuration have a half life? (If you have the time to have a discussion with me, please answer as briefly as possible, as that will allow for a more efficient dialogue. Often a person will write a page to me, and I because I don’t understand a very basic thing, the person’s efforts go to waste)
The mass listed on the periodic table is intended to account for naturally occuring isotope abundances.
I’m not quite sure what you’re referring to here. For instance, consider the large version of the Periodic table on wikipedia. Each element has a mass number. Is that what you are referring to? If so, then I have a vague idea of what you’re aiming at, and maybe we can discuss that.
So for example if you had 20 tonnes of carbon, some of it would be carbon-12, some carbon-13, some carbon-14, etc.
I think I see what you mean here. In any given tangible amount of element: Gold, Silver, Iron, Carbon, etc: you will find that the tangible element consists of individual elements that slightly vary. Is that what you mean?
The known ratio of naturally occurring abundances is reflected in the stated “average” weight on the periodic table.
You lost me here. Based on the periodic table that I linked to above, where can I see this average weight? Does each element have an average weight? Are you equating the average weight with the atomic mass?
