They are formed inside of stars.
All of them. There are no elements lighter than hydrogen. It has only two atomic particles, and you cannot have an element with less.
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.

Heavier elements like carbon, oxygen, and iron were formed in the cores of stars through nuclear fusion processes. When massive stars exhaust their fuel, they go supernova, releasing heavy elements into space. These elements then become part of new stars and planets, including Earth.
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.
Common elements like hydrogen and helium were primarily formed during the Big Bang, the initial explosive event that created the universe. Elements heavier than helium are formed in the cores of stars through nuclear fusion reactions. Very heavy elements are produced in supernova explosions.
hydrogen, helium, and a small amount (less than 2%) of heavier elements
Elements heavier than iron are formed in super-nova explosions.
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.
All of them. There are no elements lighter than hydrogen. It has only two atomic particles, and you cannot have an element with less.
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.

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.
Close, but not exactly. Hydrogen is not formed by nuclear reactions in stars, hydrogen was formed not long after the Big Bang, when the expanding universe had cooled sufficiently that an electron and a proton could combine to form a hydrogen atom. Helium and all the other elements that are heavier than hydrogen, were formed by the process of nuclear fusion, in stars.

Most natural elements are formed in stars through nuclear fusion processes. In the cores of stars, hydrogen atoms fuse to create helium and, in larger stars, heavier elements up to iron are produced. Elements heavier than iron are typically formed during supernova explosions, where the intense energy allows for the fusion of heavier nuclei. Additionally, some lighter elements are formed in processes like cosmic ray spallation and during the Big Bang nucleosynthesis.
Supernova form heavier elements
Elements heavier than iron are formed through processes like supernova explosions, where the intense heat and pressure create conditions for nuclear fusion to occur, leading to the synthesis of heavier elements. This process is known as nucleosynthesis and is crucial for the creation of elements like gold, uranium, and beyond in the universe.
