When we first learn about atoms, we learn that the simplest has one electron buzzing around one proton, aka hydrogen. But it turns out there's an atom that's even simpler than this. It's called muonium, and it's an atom that's partially made of antimatter!

I'm honestly interested in how muonium would interact with other objects. It's inherently unstable, so I'd wonder what would happen before (and perhaps during) the inevitable decay. An electron (and positron from the antimuon) would fling off free to bump into any atom that's there. Muonium may actually be worth more research. It may hold some understanding into basic molecular forces/interactions

So is positronium also element zero since they are analogous? They are radioisotopes of hydrogen and it would be a stretch to call them quasi-atoms. Back in 1960 when it was first discovered they thought it was an atom but our understanding of particle physics has significantly increased. What this video is saying is true only if it also 1960. Also, muonium and positronium have never been observed and are theoretical. To end in -ium requires the positive particle to be bound with a negative particle and the positive particle would have -ium added to the end of the name. If this is not the cause it is ends in -on. If they do exist, they would not be placed in the standard model so hydrogen would remain the lightest atom.

I'm pretty sure positronium is an even lighter form of "hydrogen", just an anti-electron (positron) replacing the proton instead of a muon. It does have a shorter lifetime than muonium, about 0.1 millionths of a second (100 ns) but it was produced at CERN as a part of the AEgIS experiment which, funny enough, is also trying to determine if antimatter falls up.

@@viorp5267 that minimum lifetime is 10 femtoseconds (10^-14 seconds) Muonion has a lifetime of 2.2 microseconds (10^-6), about 200 million times longer than the necessary lifetime.

Very cool video. I received my PhD in muonium chemistry and have been working in the field since 1998, so it's very cool to see a video on this subject. Mu behaves chemically like atomic hydrogen and we study it for two different reasons. One is that we are interested in seeing what effect the light mass of Mu has on reactions (isotope effect). This can tell us a lot about how a reaction proceeds. We also study Mu under conditions where it is difficult to study H, such as in supercritical water. One point to note, at 3:53 the slowing down of muons through a degrader is described. Usually we don't do that. Instead we frequently use surface muons, which are produced from the decay of pions at the surface of the muon production target. These have an energy of about 4 MeV and stop in about 1 mm of water. A thin degrader of condensed noble gases is used to produced low energy muons at the Paul Scherrer Institute in Switzerland. There they can produce a muon beam with energies of a few keV and can stop in tens to hundreds of nanometers. The muon beams are 100% spin-polarized and we use a form of magnetic resonance known as μSR to study the various chemical states involving muons as probes of materials. μSR is about 10 orders of magnitude more sensitive than conventional magnetic resonance techniques.

Well... the truth is, antimatter _isn't_ pretty much the opposite of regular matter. It's exactly the _same_ as regular matter, except with the opposite electrical charge. Very few scientists actually believe there's any meaningful chance that antimatter will genuinely "fall up". Some experiments are done in hopes of discovering something wild or of confirming a theory. Others are done in the name of thoroughness. The antimatter gravity experiment is one of the latter. Technically it's _possible_ to contrive a version of reality in which antimatter for some reason behaves differently with respect to gravity from matter. Since it's possible, we should test it to be sure, which we are, but it's more of a "let's just make sure the universe makes sense" sort of experiment. You're definitely not the only one to think of it, though! And if it does genuinely happen that way, it would be mind-blowing and incredible and basically open up all kinds of Star Trek like possibilities! Buuuut, probably not, sadly.

A theory is a lot more than a random combination of words that pops into your head. People have known about muonium, positronium, etc. for longer than you've been alive (probably). And they didn't figure it out by going "do ya reckon there might be lighter elements?" They established the mathematical framework of quantum field theory and made gigantic experiments to understand our universe. And then they made the very simple conclusion that an electron would orbit the muon just like it would a nucleus.

The question this brings to mind for me is, how do we determine what is matter and what is antimatter? It's easy for anything made out of electrons and quarks - that's what _we're_ made of, so antimatter is the opposite. But how does it work for muons and other, separate fundamental particles? If nothing is made of them and the only difference between a given fundamental particle and its antiparticle is the charge, how do we decide which is which? This occurred to me because I thought it was very interesting that the _muon_ forms stable configurations with _anti_ electrons while the _anti_ muon forms stable configurations with _regular_ electrons. Why don't we just call the first one an anti muon and the _second_ one a muon?

Not that weird, just a pair of neutrinos to conserve the lepton numbers. An antimuon most often decays to an antimu-neutrino, an electron-neutrino, and a positron, which annihilates the electron.

Muonium is just as unstable, because unlike the instability of chemical bonds or atomic nuclei, muons decay via the weak force. Chemical bonds are broken because of the electromagnetic force (the state of the bond was less electrically favorable than the outcome), and radioactive nuclei split apart because the strong force can't hold them together tight enough. So atoms are good at dealing with the strong and the electromagnetic force- like, that's what chemistry and nuclear physics are about -but they don't really have anything to do with the weak force. So the muon inside of Muonium decays just the same. Hypothetically, if the muon didn't decay, muonium would be quite stable electrically. It wouldn't experience the strong force, because its "nucleus" is a single lepton, but it would have an electrically stable conformation and could react with stuff pretty similarly to atomic hydrogen.
