Nuclear fusion produces certain isotopes of the lighter elements, ranked by atomic number from helium (2) up to zinc (30). When elements up to iron (26) are fused with a helium nucleus (alpha particle) or a deuterium, they release energy, and this energy helps the star continue with more fusion reactions. The isotopes of cobalt (27), nickel (28), copper (29), and zinc (30) produced by fusion are not stable and decay back into lighter elements. Iron-56 (atomic number 26) is the heaviest stable isotope produced by exothermic fusion and subsequent decay.
Our sun produces mostly helium by fusion, but it also uses fusion to make lithium, beryllium and boron. Temperature and mass determine how far a star can go with fusion. Our sun has a core temperature less than 16 million degrees Kelvin. In a star where fusion results in iron, the core temperature has to be over 2.5 billion degrees Kelvin, and this only happens in the final hours or days of the massive star's life, which then ends in a type II supernova. Half the elements with atomic numbers higher than iron are produced during the days- or months- long explosion, but it's not nuclear fusion doing it (which is exothermic), but rather processes known as nuetron capture or proton capture(which are endothermic).
What else can I help you with?
Helium can combine with what to form new substances?
helium does not combine with any element
Is helium inside a balloon a compound?
No, helium inside a balloon is not a compound. Helium is a chemical element and is the second lightest element on the periodic table. It exists as individual helium atoms inside the balloon.
During a nuclear fusion hydrogen atoms are fused into?
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.
What form is helium?
Helium is a chemical element, and its most common form is a gas at room temperature and pressure.
Nuclear fusion powers the Sun. What elemnts in the sun are fused together in the sun?
In the Sun, hydrogen nuclei are fused together to form helium in a process called nuclear fusion. This fusion process releases a large amount of energy in the form of light and heat, which powers the Sun and sustains its brightness.
When the nuclei of hydrogen and lithium are fused together what element is produced?
When the nuclei of hydrogen and lithium are fused together, helium is produced.
Is helium a form of matter?
Helium is a gaseous chemical element.
When hydrogen fuses with hydrogen what new element does this produce?
When hydrogen is fused in the suns core Helium is produced.
Where is hydrogen fused into helium?
Hydrogen is fused into helium in the core of stars through a process called nuclear fusion. This occurs under extreme temperatures and pressures, allowing hydrogen atoms to combine to form helium, releasing a tremendous amount of energy in the form of radiation.
Why helium is an element?
Helium is an element because it contains only one atom in its simplest form.
What element is transformed in nuclear fusion in the sun's core?
We understand that hydrogen atoms are fused into helium in the sun's core.
What percent of hydrogen is fused to helium in the sun and what percent is fused to energy?
99.993 % into Helium, .007 % into energy.
What role does hydrogen play in nuclear fusion?
Hydrogen is what gets fused together to form Helium.
Helium can combine with what to form new substances?
helium does not combine with any element
Is helium inside a balloon a compound?
No, helium inside a balloon is not a compound. Helium is a chemical element and is the second lightest element on the periodic table. It exists as individual helium atoms inside the balloon.
What gas is the center of the sun made of?
- hydrogen nuclei waiting to be fused into helium and - helium which has been fused from hydrogen nuclei
What is an element found in the form of a light gas?
Helium
