WebHelium has eight isotopes with mass numbers from 3 to 10 out of which two are naturally occurring stable isotopes-helium-3 and helium-4 with respective proportions of 0.0001% and 99.999%. Helium also has three short-lived radioactive isotopes. Production Helium can be obtained by heating monazite sands at 1000°C (1832°F).

Web30 mei 2024 · Updated on May 30, 2024. Stellar nucleosynthesis is the process by which elements are created within stars by combining the protons and neutrons together from the nuclei of lighter elements. All of the atoms in the universe began as hydrogen. Fusion inside stars transforms hydrogen into helium, heat, and radiation. WebHelium is an electron-filled element. The last orbit of helium is full of electrons. Therefore, helium is an inert element and helium atoms are more stable. Therefore, helium atoms do not want to become ions very easily. It takes a lot of energy to turn a helium atom into an ion. The ionization energy of helium is 2372.3 kJ/mol and 5250.5 kJ/mol.
