The sun.
When the nuclei of hydrogen and lithium are fused together, helium is produced.
When helium and hydrogen are fused together in nuclear reactions, energy is produced along with heavier elements like carbon and oxygen. This process is known as nucleosynthesis and is a key mechanism in the evolution of stars.
Helium is heavier than hydrogen. Hydrogen is the lightest and simplest element in the periodic table, while helium is the second lightest element.
Hydrogen is about 7 lighter than helium.
Hydrogen and helium are the two most abundant elements in the universe.
- hydrogen nuclei waiting to be fused into helium and - helium which has been fused from hydrogen nuclei
99.993 % into Helium, .007 % into energy.
When the nuclei of hydrogen and lithium are fused together, helium is produced.
Nuclear fusion, in which hydrogen-1 is fused into helium-4.
Hydrogen is fused into helium in the core of the sun, where temperatures and pressures are high enough to initiate nuclear fusion reactions. The core is where the sun's energy is produced through the fusion of hydrogen nuclei into helium nuclei.
Hydrogen is what gets fused together to form Helium.
As a star ages, it fuses hydrogen into helium in its core. Therefore, helium becomes more abundant in older stars compared to younger stars.
During nuclear fusion, hydrogen atoms are fused into helium atoms. This process releases a large amount of energy in the form of heat and light. It is the same process that powers the sun and other stars.
The sun's light is the result of a nuclear fusion reaction by which hydrogen is fused into helium.
When helium and hydrogen are fused together in nuclear reactions, energy is produced along with heavier elements like carbon and oxygen. This process is known as nucleosynthesis and is a key mechanism in the evolution of stars.
Hydrogen: the mutual fusing of H atoms into Helium, with consequent release of energy.
The ratio of hydrogen to helium in the sun has been decreasing over time as hydrogen is being converted into helium through nuclear fusion reactions in the sun's core. This process is gradually shifting the composition of the sun more towards helium.
