Heavy elements are primarily produced in the cores of massive stars through nuclear fusion processes during their lifetimes. Elements heavier than iron are often formed through supernova explosions, where the intense heat and pressure create the conditions necessary for the fusion of lighter elements. Additionally, elements like gold and platinum can also be produced in neutron star collisions, where the rapid neutron capture process, or r-process, takes place.

The building blocks of the universe are called?
The building blocks of the universe are called atoms. Atoms are made up of protons, neutrons, and electrons. These particles interact to form all the elements and matter in the universe.
What are all of the gas giants atmosphere made up of?
Mainly hydrogen and helium - which were also the main elements in the early Universe.
What are the 5 most abundant elements that make up atomic matter in the universe and what approximate percentages do they occur?
The 5 most abundant elements in the universe are hydrogen (about 75%), helium (about 23%), oxygen (about 1%), carbon (about 0.5%), and nitrogen (about 0.3%). These elements make up the majority of atomic matter in the universe.
99 percent of the known matter in the universe?
is found in the form of hydrogen and helium. These elements were created during the Big Bang, and all other elements found in the universe were formed through processes like nuclear fusion in stars. Only a small fraction of the universe is made up of heavier elements like carbon, oxygen, and iron.
Most of the visible universe if made of?
Most of the visible universe is made up of hydrogen and helium. These elements were formed during the Big Bang and make up about 98% of all visible matter in the universe.
What is first elementslight elements and heavy elements?
The light elements in the universe, such as hydrogen and helium, were created during the Big Bang. Heavy elements, like carbon, oxygen, and iron, were formed in the cores of stars through nuclear fusion processes.
What are inner planets made of?
Heavy elements.
How were the heavy elements from iron to uranium made?
Up to uranium elements are made by stellar nuclear synthesis; after uranium elements are man made.
What would the chemical composition of the Universe be like if the only nuclear reactions that had ever occurred in stars had been those involved in energy production?
All elements heavier than iron are made by nuclear reactions that consume energy rather than producing it, so the universe that you describe would have no heavy elements.
How would the universe be different if massive starts didnt explode?
We wouldn't have the heavy elements... and as a result, we wouldn't exist.
Where in the universe are heavy elements with masses greater that that of helium being produced today?
In the interior of certain massive stars.
The building blocks of the universe are called?
The building blocks of the universe are called atoms. Atoms are made up of protons, neutrons, and electrons. These particles interact to form all the elements and matter in the universe.
Are all chemicals made in the sun?
The universe is made of hydrogen with a small percentage helium. Elements heavier than helium are made in stars (not only the Sun). We will never see any heavy elements made by our Sun, but perhaps some civilization will. The elements we use, up to iron in atomic weight are made in stars by fusion during their normal lifetimes. Elements heavier than iron are made only when stars explode. The earliest solar systems in the early universe consisted only of hydrogen and helium. We live in a solar system since made of material tht has recycled once or twice since we know that the rubble surrounding our Sun has iron and heavier elements.
Why is it likely that life did not form during the very early history of the universe?
In the early Universe, there were no heavy elements around - all the matter of the Universe was in the form of hydrogen, helium, and small amounts of lithium; until the first stars formed, created these heavier elements, and put them out into space when they exploded as supernovae.
How would the universe be be different if massive stars did not explode at the ends of their lives?
Well neither, you or I would exist. Without the influx of heavy elements, the Universe would be a very sterile place.
Why do astronomers believe that globular clusters are made of old stars?
Astronomers believe that globular clusters are made of old stars because they contain mainly low-mass, low-metallicity stars that are typically found in older stellar populations. The lack of heavy elements in these stars suggests they formed early in the history of the universe when these elements were scarce. Additionally, globular clusters are commonly found in the halos of galaxies, where older stars are more prevalent.
What element has the most effect in universe?
Hydrogen - from it all other elements are made in the stars
