Question

Can we react H And HE? If yes.
how?

Answer 1

the secret of helium’s nobility, that filled outer shell, it should be no surprise that helium hydride is only stable as an ion, meaning that there are still only two electrons involved, but one is shared in a covalent bond between helium and the proton that is a hydrogen nucleus. The neutral molecule can briefly exist, but only as an excimer, where the excess electron has enough energy to keep it at a higher level.

Although not the kind of substance to be found on the lab shelf, helium hydride is an acid. In fact the proton affinity of the base – the energy given out when helium reacts with a proton – is the lowest known, technically making helium hydride the strongest acid in existence. This is arguably an obscure substance with no useful application, so it may seem strange that helium hydride has anything more than a passing mention in the chemistry textbooks. However, it could well be that helium hydride was the first compound ever to exist.

For the first couple of minutes after the Big Bang, 13.7 billion years ago, there was no matter as we now know it.

What began as an inferno, so energetic that no particles could stay in existence, cooled and expanded to first form a ‘soup’ of quarks and their exchange particles, gluons, and finally became sufficiently cool for ions to form. Once hydrogen, the most common element, had formed, deuterium came soon after it. This in turn made it possible for the more stable helium 4 to form from the fusion of two deuterium ions. There was also a little lithium, but for our purposes, the important aspect is that just minutes into the existence of the universe there were hydrogen and helium ions present, in a rough ratio of twelve to one.

Answer 2

Helium is a non reactive stable gas. Therefore there's no compound of it in nature
