They were formed in supernovae.
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.
All the compounds existing in the universe are formed.
Most likely while everything was being blown away, materials, mostly hydrogen, were pushed into each other because of gravity and the force of the big bang, exchanged protons, neutrons, and electrons, forming new elements.
Uranium is formed through the process of supernovae, where heavy elements are created by nuclear reactions in the hot, dense cores of dying stars. These heavy elements are then scattered into space when the star explodes, eventually forming into uranium-rich mineral deposits on Earth through geological processes.
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.
They were formed in supernovae.
Heavy elements were formed in stars, and blown out into space in supernova explosions.

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.
Such elements are formed within stars. The heavy elements which are currently here on Earth were formed in stars some time ago, and then they were blown into space in supernova explosions.

Heavier elements in the universe are primarily formed through nuclear fusion processes within the cores of stars. Elements beyond iron are typically formed in supernova explosions, where the extreme conditions allow for the synthesis of elements such as gold, silver, and uranium.
