Hydrogen is the simplest atom, consisting of just one proton in its nucleus. It was the only element present after the Big Bang. Hydrogen has an atomic number of 1, melting point of -259.34°C, and plays an important role as a source of energy in stars through nuclear fusion reactions. It is also used industrially to process fossil fuels and produce ammonia and methanol.

2. About Hydrogen
 Hydrogen is the
simplest kind of atom
 in the very earliest
days after the Big Bang
hydrogen was the only
kind of atom in the
new Universe

4. Sources of Hydrogen
 Hydrogen element is
found in the stars, and
plays an important part
in powering the
universe through both
the proton-proton
reaction and carbon-
nitrogen cycle.

5. Uses of Hydrogen
 to process fossil fuels
 to produce ammonia- used
in common household
cleaning products.
 used as a hydrogenating
agent to produce
methanol and convert
unhealthy unsaturated
fats and oils to saturated
fats and oils.
