Eli5: Is it possible that there are elements on other planets, we don’t have on earth and haven’t discover yet?
In: Chemistry
On planets no not realy. An element is define by its number of protons and we have discovered all elements up to 118 protons. But every element with such high and even higher protons is incredibly unstable, so it decays in miliseconds or less. Now there is the possiblity that other elements are created with the merger of neutron stars but those will also decay very fast.
