The most abundant elements in the universe - Hydrogen (H) and Helium (He):
Hydrogen (H) is the lightest and the most abundant element in the universe, it has one proton, no neutron and one electron with an atomic number of 1, it is a colourless, odourless, tasteless, and highly flammable, diatomic gas.
Helium (He) is the second most abundant element in the universe, it has two protons, two neutrons and two electrons with an atomic number of 2, it is a colourless, odourless, tasteless, non-toxic, inert, monatomic, noble gas - the first in the noble gas group. It is the smallest and the lightest noble gas.
Fusion is the process that powers the sun and the stars:
The fusion of Hydrogen nuclei uses up Hydrogen (H) to produce Helium (He) and energy, Hydrogen is the fuel for the process. This is called nuclear fusion. Fusion is the process that powers the Sun and the stars. It takes four Hydrogen (H) atoms to fuse into each Helium (He) atom. During the process some of the mass of the Hydrogen is converted into energy. Thus fusion has the potential to be a limitless source of energy. As the Hydrogen is used up, the core of the star condenses and heats up even more.
The noble gases - the majestic gases don't likely to react with anything:
The noble gases, also called inert gases or aerogens, are all odourless, colourless, monatomic gases with very low chemical reactivity. Helium (He) itself is a noble gas making it very unlikely to combine with any other kind of atom.
The universal birth of chemistry- Hydrogen (H) bond to Helium (He):
A Helium (He) atom bonded to a Hydrogen (H) atom 'one electron removed' produce Helium hydride (HeH+). It is viewed as protonated helium. It is the lightest heteronuclear ion, and is known to be the first compound formed in the Universe after the Big Bang; at a time called the 'dawn of chemistry'. It is a positively charged stable molecule and the strongest acid known. Scientists have deduced from evidence and reasoning that Helium Hydride (HeH+) was the first, primordial molecule in the Universe. It is an excessively particular molecule.

The Universal birth of Chemistry - Helium hydride (HeH+):
Anything before the Big Bang in a question:
Space & the Universe is expanding at an ever accelerating speed, this indicates once the Universe was smaller than it is now; up to a point form.
A state prior to the Big Bang necessarily needs to be a point form, having no dimension, besides space and time (those we know) cannot be there before the Big Bang. Prior to the Big Bang, it was a no dimensional singularity with gravity infinite.
Immediately after the Big Bang and before a non-inflationary time classified as a Planck time i.e. 10^-43 seconds, it was not possible for any subatomic particles - e.g. nuclei, electrons or photons - to be existed then, it was too hot and dense for any particles to be stable, as all the known form of interactions must be united then as gravity - in absence of anything intractable; either through strong or weak nuclear interactions, or electromagnetic interaction, except gravitational interaction, - but then the first quarks formed.
