Nuclear fission had been discovered. However, only Otto Hahn was awarded the Nobel Prize in Chemistry in 1944 for this discovery.<\/p>\n\n\n\n<p>The study of nuclear fission is considered part of the fields of nuclear chemistry and physics.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"507\" height=\"255\" src=\"https:\/\/wp2.rinconeducativo.org\/wp-content\/uploads\/2016\/12\/fision.gif\" alt=\"\" class=\"wp-image-6420\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>On December 19, 1938, nuclear fission was discovered<\/p>\n","protected":false},"author":1088,"featured_media":10442,"template":"","meta":{"_acf_changed":false,"footnotes":""},"tags":[7560,8230,7715,7146],"mes":[7210],"clasificacion_anterior":[7255],"class_list":["post-20690","re_efemeride","type-re_efemeride","status-publish","has-post-thumbnail","hentry","tag-atomo-en","tag-nuclear-energy","tag-periodic-table-en","tag-radiation-en","mes-december"],"acf":{"fecha":"19381219"},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.8 -
