Up to uranium elements are made by stellar nuclear synthesis; after uranium elements are man made.
Elements with atomic masses greater than uranium are typically produced in supernova explosions, where high-energy processes enable the fusion of heavy nuclei. This process can lead to the creation of transuranic elements such as neptunium, plutonium, and beyond. Additionally, elements beyond uranium can also be artificially synthesized in particle accelerators through nuclear reactions involving target nuclei.
elements after uranium (atomic number 92) are all artificially made.
Heavy elements.
No. Alloys are mixtures made up of elements like:steel- made up of iron and carbon. Iron and carbon are elements but steel isnt.
Heavy elements are primarily made through nuclear fusion processes inside stars. Elements heavier than iron are typically formed in supernova explosions, where the intense pressure and heat create the conditions for nuclear reactions to produce these elements. Additionally, some heavy elements are formed through neutron capture processes in cosmic events like neutron star mergers.
Uranium is not made of any material because Uranium is an element and elements are not made of something else.
The core of the earth contains many elements, not just two.However the two most abundant elements in the earth's core are nickle and iron (the final two elements that a star can make by fusion before it dies).But there are many other elements in the core, especially ones with atomic masses greater than that of nickel and iron. Many of these heavy elements are radioactive (e.g. radium, thorium, uranium) and it is the heat generated by the decay of these heavy radioactive elements that keeps the core hot and the outer core liquid.
Iron co2 silicon oxygen potassium .... and lots of other stuff hi!
It is estimated that about 1% of the mass of the sun is made up of heavy elements, which would include uranium. However, the exact amount of uranium present in the sun is difficult to determine due to the extreme conditions in its core.

Man-hole covers (inspection covers) are made from heavy, thick cast-iron. Gates can be made from wood or metal.
Fortunately, no !
In the universe they are initially made in supernova explosions. These then become parts of other stars, planets and celestial bodies. Some are radioactive and decay into daughter elements which are usually after iron.

Uranium is an element; it cannot be 'made' as it were. It is similar to iron or oxygen in that respect.Only supernova explosions are powerful enough to actually make uranium or any element heavier than nickel and iron. Some uranium can be made in nuclear breeder reactors or in labs by bombarding thorium samples with neutrons.
No, iron is not the heaviest element made in massive stars. Massive stars produce elements through nuclear fusion in their cores, creating heavier elements than iron, such as lead, gold, and uranium. Iron is often referred to as the endpoint of nuclear fusion in massive stars because the energy required to fuse iron exceeds the energy output of the reaction.
Iron is, itself, and element. It is not a compound of two elements.
