This is why some scientists consider muonium to be the lightest form of hydrogen! and just like other forms of hydrogen, like deuterium and tritium, chemists gave muonium an honorary chemical symbol: mu. if you prefer to think about muonium as its own element, and not like a quirky kind of hydrogen, that could make muonium the simplest element.
This is still a pretty good deal, as it gives us a universe made of about 75% hydrogen, 25% helium 4, about 0.01% deuterium and helium 3 each, and approximately 0.0000001% lithium. Nucleosynthesis. diagram illustration the creation of new elements by the alpha process. nucleosynthesis is the process that creates new atomic nuclei from pre existing nucleons (protons and neutrons) and nuclei. according to current theories, the first nuclei were formed a few minutes after the big bang, through nuclear reactions in a process. So almost all of those neutrons went into the production of helium 4. from calculations like this, cosmologists can predict that the universe started out with a mixture of roughly 75% hydrogen. Aboutabout this video. transcript. discover how the universe, once filled with just hydrogen and helium, evolved to contain a variety of elements. learn how the death of massive stars, through a process called supernova, creates new elements, scattering them across the cosmos and setting the stage for complex life. created by big history project.

Nucleosynthesis is the creation of new atomic nuclei, the centers of atoms that are made up of protons and neutrons. nucleosynthesis first occurred within a few minutes of the big bang. at that time, a quark gluon plasma, a soup of particles known as quarks and gluons, condensed into protons and neutrons. after the universe cooled slightly, the. Tennessine. tennessine is a synthetic chemical element; it has symbol ts and atomic number 117. it has the second highest atomic number and joint highest atomic mass of all known elements and is the penultimate element of the 7th period of the periodic table. it is named after the region of tennessee, where key research institutions involved in.
