According to the CERN site, after the "Big Bang", it took 380,000 years for the first atoms to form from electrons trapped in orbits around nuclei. These were mainly helium and hydrogen electrons. It took about that amount of time for the universe to expand and cool - and in general, for conditions to be just right for the next event.
What else can I help you with?
When is An ion is formed when an atom?
An ions is formed when an atom gains or loses electrons.
The nucleus of a hydrogen atom is formed by?
The nucleus of a hydrogen atom is formed by a single proton.
What is an atom that gains and loses an electron and has an electric charge?
When an atom gains electrons, negatively charged anions are formed. When an atom loses electrons, positively charged cations are formed.
Was carbon the first atom created after the big bang theory?
No, carbon was not the first atom created after the Big Bang. The first atoms that formed were hydrogen and helium, and heavier elements like carbon were produced later through processes like stellar nucleosynthesis in the cores of stars.
What makes up the centre of an atom in chemistry?
The center of the atom is the nucleus formed from protons and neutrons.
How was the first hydrogen atom formed?
The first hydrogen atom was formed during the recombination era of the early universe, around 380,000 years after the Big Bang. As the universe cooled down, protons and electrons combined to form neutral hydrogen atoms. This marked the transition from a plasma of charged particles to a transparent universe.
What particles is the atom formed of?
Atom is formed of electrons, protons and neutrons.
When is An ion is formed when an atom?
An ions is formed when an atom gains or loses electrons.
An ion is formed when am atom?
An ions is formed when an atom gains or loses electrons.
When are ions formed?
Ions are formed when an atom gains or loses electrons. When an atom loses electrons the Ion that is formed has a positive charge.
What is the bond angle formed by an axial atom the central atom and any equatorial atom?
The bond angle formed by an axial atom, the central atom, and an equatorial atom in a trigonal bipyramidal molecular geometry is approximately 90 degrees.
The nucleus of a hydrogen atom is formed by?
The nucleus of a hydrogen atom is formed by a single proton.

What kind of chemical bond is formed when electrons are transferred from atoms to atoms?
A covalent bond is formed when electrons are transferred from atom to atom.
