Where can I find a copy of the periodic table of elements?

Yeah I know about google. What I’m looking for is how the elements were formed. Like hydrogen formed in the Big Bang and helium forms in stars.

Periodic table....

Most periodic tables do not give information about the "formation" of the elements. You will need a different source.

What you want to know about is "nucleosynthesis."
Start here: https://en.wikipedia.org/wiki/Nucleosynthesis

And the site includes a periodic table with information about the formation of the elements.

The Periodic Table doesn't actually give any information about how the elements were formed.

It's probable that some helium (atomic number 2), and maybe a bit of lithium (number 3), were formed in the Big Bang along with the hydrogen (atomic number 1), according to one cosmologist I've read. And you're correct that helium is also a main product of hydrogen fusion in stars.

For the most part, the elements above helium are formed in novas, the explosive events which end the lives of some stars. Of course, we also know that the really heavy elements, such as uranium and radium, are subject to nuclear decay, which splits their nuclei and forms lighter elements.

Anyway, here's a table:

These elements came into being in a way that can't otherwise be described as being born during the Big Bang.

Most elements form in stars, and there are several different processes involved. You would have to research stellar evolution and nucleosynthesis to get that answer. Or get a copy of a basic geochemistry text; mine had a chapter on that. No good summary charts though. The problem is that there are often several paths to the same end. A good portion of what forms does not last more than instantaneously but can result in longer-lived secondary or tertiary products (or even further down the line). The system is very dynamic, complex.

Anywhere on Google

If you look up history of the formation of "element you want', you can usually find websites that explain it all.

One fairly good way is to look each one up on Wikipedia. Or this one is pretty good - click on the names to go deeper:

And there are many books about just the elements because they are just so darn fascinating.

You may not find one like you want, so you may have to create your own. It wouldn't be hard and might be quite interesting to research some of the less common elements.

To get you started:
Hydrogen, helium, and some lithium formed during the Big Bang.
