If a star runs out of fuel when all of the elements inside it are fused to iron how are the heavier elements created?
During the main life cycle of a star, no elements heavier than iron can be created, and that's only in very massive stars (our sun is only massive enough to fuse hydrogen into helium). Your question is a very good one, and if you thought of it on your own, you should be proud. Every element heavier than iron is created when the star dies. Specifically, when it becomes a super-nova. When all the lighter elements have been fused, the star can't generate enough energy to resist its own gravity, so it collapses in on itself. The result is a sudden gigantic spike in pressure that creates all the heavier elements. As if it weren't cool enough that we're all made from star-stuff, a good bit of us is made from supernovae, too!

What is the last stage of nuclear fusion?
A neutron star is already a dead star it can produce no more energy, although massively dense it will just continue to radiate its energy out into space until there is nothing left. There is an alternative ending for a Neutron Star and that is, if it was a part of a binary system or had enough mass collect on it could collapse further to create a Black Hole.
Where did the black star dragon balls come from?
Before Piccolo fused with god.God created the black star Dragonballs!
What is Minto and Zakuro?
they are characters in Tokyo mew mew. Zakuro is famous and is fused with a grey wolf she is my favorite. Mint ADORES Zakuro and is fused with an ultramarine lorokeet.(i think)
Is fused quartz piezo electric?
yes. back in the 15th century when alchemy was popular scientists found out the mineral quartz is piezo electri and so is fused quartz
What happens when a bulb gets fused?
When a bulb fuses the circuit is broken if it is on a serial circuit. If the bulb is on a parallel circuit, only the fused bulb will go out, any other bulb would remain lit. On a serial circuit, until the bulb is replaced by a new one, the circuit is not able to be used.
Why is iron the only element that can be produced in stars?
All elements (except hydrogen) are produced in stars through nuclear fusion (under tremendous heat, two hydrogen atoms fuse into one helium plus release pure energy). When the hydrogen is all fused, helium is fused into heavier elements at a higher temperature, then those are fused and so on until we get to iron. Iron is the element that will cause a star to collapse and then explode violently in a supernova. The explosion causes further fusion and creates still heavier elements.
Where elements up to carbon nitrogen and oxygen are fused?
Elements up to carbon, nitrogen, and oxygen are fused in the cores of massive stars during stellar nucleosynthesis. The fusion process combines lighter elements into heavier ones, releasing energy in the form of heat and light. This fusion creates elements like neon, magnesium, silicon, sulfur, and iron.
Which nuclear fuel is there in the sun?
At this point in time hydrogen is being fused into helium. Many, many years down the line, as the hydrogen runs out, the sun will begin fusing heavier and heavier elements for fuel. At least to iron.
How do scientists postulate that the phosphorus on earth was created?
Scientists believe that phosphorus on Earth was created through nucleosynthesis in the core of massive stars, where lighter elements were fused together under high temperatures and pressures. This process enriched the universe with heavier elements, which were then scattered into space through supernova explosions and eventually incorporated into planets like Earth.
Stars combine Hydrogen to make Helium during nuclear fusion. Living things are made of heavier elements like Carbon Oxygen Iron and Calcium. How did these elements form?
These heavier elements were formed through processes like nucleosynthesis in the core of massive stars, supernova explosions, and stellar winds. These events create conditions where lighter elements are fused or broken apart to form heavier elements, eventually leading to the creation of elements like carbon, oxygen, iron, and calcium.
How do heavier elements on the periodic table form?
A few elements past iron can form in the star by neutron capture and beta decay. However the majority can only be formed by the blast shockwave of a supernova, which can form elements significantly beyond Uranium.
What are supernovas made of?
they are made from millions of kitfoxes
Is fusion an endothermic reaction?
It depends on what is being fused. Fusion usually takes place with elements lighter than iron, mostly hydrogen. in those cases it is exothermic. Fusin elements heavier than iron is endothermic.
What is the heviest element that can be made in stars center?
While it is still a star? Iron. Everything heavier must be fused from lighter elements in a supernova explosion, which blows the star apart.
How are heavier metals formed?
The heaviest of all elements are formed by bombardment of two ions into each other ( eg Zinc and Lead) which then forms a highly unstable heavy element that very rapidly decays into smaller elements.
Explain how heavier elements are formed from hydrogen within the core of a star?
Heavier elements are formed through nuclear fusion reactions in the core of a star. Hydrogen atoms are fused together under high pressure and temperature to form helium. Further fusion reactions involving helium nuclei lead to the formation of heavier elements like carbon, oxygen, and up to iron. These elements are produced through a series of nuclear reactions that occur as the star evolves.
How does stars light up?
Inside stars atoms are fused together to form heavier elements in a process called nuclear fusion. Our very own Sun is our closest star. Our Sun fuses hydrogen atoms together to form helium. Our Sun will eventually produce heavier elements when it reaches a certain age, and will in fact create even heavier elements as it dies! This process of fusion releases energy in the form of heat and light. The light travels from the star to your eye and you can see it. Interestingly, because light takes time to travel this distance, when you look at stars you are actually seeing them as they were in the past.
