How the elements were formed
NettetHow the elements found in the universe were formed. The lightest elements (hydrogen, helium, deuterium, lithium) were produced in the Big Bang nucleosynthesis. According to the Big Bang theory, the temperatures in the early universe were so high that fusion reactions could take place. This resulted in the formation of light elements: … Nettet12. aug. 2014 · Around 13.8 billion years ago, all the matter in the Universe emerged from a single, minute point, or singularity, in a violent burst.

NettetFigure 16.9: The lightest elements were formed in the first few minutes of the Universe. Only elements up to beryllium would have been produced because gaps at masses of 5 and 8 create roadblocks that slow nuclear reactions. It is possible that a very small amount of 9 Be was made, though a primordial abundance has not been detected. NettetScientists believe that the Solar System was formed when a cloud of gas and dust in space, made up of elements formed deep within stars, started to collapse, forming a solar nebula. This began to spin as it collapsed, eventually giving birth over billions of years to the Solar System as we know it today.
NettetA version of the periodic table indicating the origins – including big bang nucleosynthesis – of the elements. All elements above 103 ( lawrencium) are also man-made and are not included. Big Bang nucleosynthesis produced very few nuclei of elements heavier than lithium due to a bottleneck: the absence of a stable nucleus with 8 or 5 nucleons.
