Big Bang in a Diagram

Electrons join with protons and neutrons to structure molecules, generally hydrogen and helium. Light can at last sparkle. Gravity makes hydrogen and helium gas blends to shape the goliath mists that will come to be cosmic systems; more modest bunches of gas downfall to structure the first stars. 

As galaxies cluster together under gravity, the first stars die and spew heavy elements into space. These will eventually form into new stars and planets.
