The most common element in the universe is hydrogen.
The most abundant element in the universe is hydrogen.
Astronomers believe that hydrogen is the primordial element in the universe because it is the most abundant element and simple in structure. Hydrogen was the first element formed after the Big Bang and is a key component in the formation of stars and galaxies. Observations of the cosmic microwave background radiation also support the idea that hydrogen is the oldest element in the universe.
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.
Helium and metals (which basically means any element heavier than helium) are formed in the star's core.
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.
Because hydrogen was the ffirst element formed in the first 3 minutes of the universe.
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.

Hydrogen is considered the primordial element in the universe because it is the most abundant element, making up about 75% of the universe's elemental mass. It is thought to have been the first element to form after the Big Bang, leading to the creation of stars and eventually heavier elements through nuclear fusion processes.
