Web13 okt. 2007 · Iamu. The wikipedia article on Bose-Einstein condensates mentions that helium-4 is, or can be, a boson. It says that a condensate is made by putting many bosons, such as helium-4, into the lowest energy state. How can an atom be a boson? I figured that an atom, composed of fermions, would have to be a fermion as well. WebThe answer to this question is 18 electrons. The electrons of an atom tend to fill all the lowest energy levels first and the higher ones after that. This order of filling gives the electrons the lowest possible energy state. We can understand this point if we consider a helium atom first and a lithium atom second. chowchilla memorial healthcareWebOnce the helium-3 has been produced, there are four possible paths to generate 4 He . In p–p I, helium-4 is produced by fusing two helium-3 nuclei; the p–p II and p–p III branches fuse 3 He with pre-existing 4 He to form beryllium -7, which undergoes further reactions to produce two helium-4 nuclei. gengar themed keyboard
