Forming elements heavier than iron and nickel requires the input of energy. Super nova explosions result when the cores of massive stars have exhausted their fuel supplies and burned everything into iron and nickel.
The star then collapses and explodes. Nuclei with mass heavier than nickel (gold, silver, lead, uranium, etc.) form in the explosions. This is called nucleosynthesis. These elements form over seconds, compared to the lighter ones that took billions of years to form, and are much rarer.
This material is thrown out into space and can end up in later generation stars and planets.

What are two atoms that are heavier than carbon?
Two atoms that are heavier than carbon are nitrogen and oxygen. Nitrogen has an atomic number of 7 and a higher atomic mass than carbon, while oxygen has an atomic number of 8 and is even heavier than nitrogen.
What elements are formed in cool stars?
In cool stars, elements such as hydrogen and helium are primarily produced through nuclear fusion in their cores. Elements heavier than helium (e.g., carbon, oxygen, and iron) are formed through nucleosynthesis processes during the later stages of a star's lifecycle, such as in red giant stars or during supernova events.
What is lighter than helium but heavier than air?
hydrogen
When The heavier elements in the universe where formed by?
The heavier elements in the universe were primarily formed through processes such as stellar nucleosynthesis and supernova explosions. In stars, nuclear fusion combines lighter elements like hydrogen and helium into heavier elements up to iron. Elements heavier than iron are typically formed during supernovae, where the intense energy and neutron capture processes create these elements. Additionally, some heavy elements may also form through the merging of neutron stars.
How is a supernova related to matter found on earth?
A supernova is a star that explodes. Stars about the size of our Sun explode when they run out of "fuel". The fuel they have is Hydrogen which they fuse into Helium and thus convert mass into energy (they shine brightly), Then the Helium and some Hydrogen are fused into heavier elements (Lithium etc) making more energy. All elements heavier than Carbon and lighter than Iron are made in the supernova explosion that comes at the end of the star's "life". Heavier stars will make even heavier elements. The Earth is mostly made of these heavier elements. We are all stardust.
What elements are heavier than hydrogen?
All of them. There are no elements lighter than hydrogen. It has only two atomic particles, and you cannot have an element with less.
Where did all the elements come from?
Hydrogen, some helium and less lithium are the result of the big bang. All the other elements are made inside the cores of stars, except for elements heavier than iron. All elements heavier than iron are created during supernova explosions.
How are elements heavier than hydrogen formed?
Elements heavier than hydrogen are formed through nuclear fusion processes in stars. When lighter elements fuse together in the intense heat and pressure within a star's core, they can form heavier elements. This process continues throughout a star's life until elements up to iron are created. Elements heavier than iron are formed through supernova explosions or in the collisions of neutron stars.
What is the sun formed from?
hydrogen, helium, and a small amount (less than 2%) of heavier elements
What are the two main elements of the sun?
Hydrogen and Helium. Also comprised of a core of much heavier elements, all the elements in the universe heavier than hydrogen probably came from supernovae.
Where did most of the elements heavier than Hydrogen and Helium form in the Universe?
Elements heavier than hydrogen and helium primarily formed in the cores of stars through nuclear fusion processes. Elements up to iron are formed in the cores of stars, while elements heavier than iron are typically produced in supernova explosions or neutron star mergers. These heavy elements are dispersed into space during these catastrophic events, enriching the interstellar medium from which new stars and planets can form.
What gas is heavier hydrogen or oxygen?
oxygen gas is heavier than hydrogen gas
How are elements formed from hydrogen?
Heavier elements are formed from hydrogen, the most abundant element in the universe, through a process called nuclear fusion. There are machines or structures in the universe that do this, and we call them stars. It is the process within stars, stellar nucleosynthesis, that allows heavier elements to be created up through iron. Elements heavier than iron are formed in supernova events.

How are elements heavier than iron are formed?
Elements heavier than iron are formed in super-nova explosions.
Are you something of starlight?
Not starlight, but the material we are made of was made in stars. All elements heavier than helium, except for a small amount of lithium, are made in stars. All elements heavier than iron come from supernovae.
Which is heavier hydrogen or helium?
Helium is heavier than hydrogen. Hydrogen is the lightest and simplest element in the periodic table, while helium is the second lightest element.
What are two atoms that are heavier than carbon?
Two atoms that are heavier than carbon are nitrogen and oxygen. Nitrogen has an atomic number of 7 and a higher atomic mass than carbon, while oxygen has an atomic number of 8 and is even heavier than nitrogen.
