They were formed in supernovae.
It is believed this was how the universe formed. Hydrogen fuses to form all the other heavier elements on the periodic table up to Element number 92
All the compounds existing in the universe are formed.
Asssuming the Universe began with the Big Bang, it is thought that the first element formed, by colliding quarks and other sub-atomic particles, was hydrogen - the lightest of all the elements.
The Periodic Table is a chart of all known elements. There is no terrestrial significance of the chart, it represents all known elements in the universe. As the materials that make up the Earth, and everything that is on it, originate as debris from exploding stars billions of years ago we can safely say that all the elements on the Periodic Table are extraterrestrial in origin.

The periodic table does. If you mean the actual elements, nothing in the universe can contain all elements at once, since many are to unstable to be formed and exist while the others are being created.

Salts are formed by combining metals and non metals.The elements of the salt are present in periodic table.
Other elements were formed in stars by nucleosynthesis.
no, but it is formed from elements. every element discovered is on the periodic table
