the energy of electrons in atoms can take on only certain values, like the energy of light, and crucially that electrons can only "jump" between one atomic orbit and another with determined energies, emitting or absorbing a photon when they jump. These are the famous "quantum leaps."

periodic table of elements … lists all the possible elementary substances of which the universe is made, … Why are precisely these elements listed there, and why does the periodic table have this particular structure ..” & the elements having these specific properties? … each element corresponds to one solution of the main equation of quantum mechanics. The whole of chemistry emerges from a single equation

The sun bends space around itself, and Earth does not turn around it because of a mysterious force but because it is racing directly in a space that inclines, like a marble that rolls in a funnel. There are no mysterious forces generated at the center of the funnel; it is the curved nature of the walls that causes the marble to roll.
