Hydrogen Expert - H2 - H3 - What about....?

Question

I've heard H2 is readily available on Earth and H3 is all over the Moon, but do H4 or higher chains exist in the universe?

Answer 1

its posible but very rare. even noble gases can be made to give up or accept electrons. im sure somewhere there is a chain like it but not any where on earth, maybe in some extreme conditions, like on the sun or very hot areas.
