WebThe star enters a steady helium-burning phase which lasts about 10% of the time it spent on the main sequence (the Sun is expected to burn helium at its core for about a billion … WebThe fusion process moves outward into a shell surrounding the hot helium core. Helium can also undergo fusion but, since it is a larger atom, it requires over a 100 million degrees of temperature to overcome its electrostatic repulsion (the helium nuclei has two protons, double the hydrogen nuclei). ... and a helium burning shell will develop ...

WebJun 10, 2008 · No. Helium is a noble gas and has a full compliment of electrons in the first 'orbit' of its atoms. This makes it very, very stable and inert. Therefore helium forms no compounds with any other element. As burning in air by definition is the reaction between the substance and oxygen in the air to form an oxide (e.g. charcoal (carbon) burns in air … WebAnswer (1 of 3): OUR SUN IS A MAIN SEQUENCE STAR and it’s OVER 90 % HYDROGEN AND HELIUM The first stars contained only hydrogen and helium and some of their isotopes.

WebIt "burns" hydrogen as in it smashes two protons together and they bond to make helium, though the actual chain has a few more middle steps. To "burn" helium is to combine helium atoms to make heavier atoms. The fact the helium is a noble gas means it's chemically stable, has nothing to do with its nuclear properties. WebMay 31, 2024 · Can you burn helium? Helium is a special gas called a Noble Gas, which means it doesn’t burn. What country has the most helium? In 2024, the United States produced the largest volume of helium worldwide. In that year, they produced 64 million cubic meters of helium, which was extracted from natural gas. Following the United … WebJan 7, 2024 · 7. Massive stars do not undergo helium flash because they have core temperatures high enough to prevent the helium core from becoming electron-degenerate. Check here for some more information. Therefore, the star can burn helium in a smooth transition, instead of undergoing helium flash. In more details, the massive star's core … small outdoor window wreaths
