How Quantum Rules Shape Chemistry

Discover the bizarre rules of the ultra-small and see how particle waves and probability clouds build the molecules of our everyday world.

Like Duolingo, but for How Quantum Rules Shape Chemistry. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through The Quantum Nature of Light and Atoms and From Atomic Clouds to Chemical Reality. It starts from scratch.

Key ideas in How Quantum Rules Shape Chemistry

  • Light energy arrives in indivisible packets called quanta
  • An atom absorbs an entire quantum of energy or none at all
  • Energy cannot be delivered in partial or fractional packets
  • A photon's color determines the energy of each individual packet
  • Ultraviolet photons carry enough punch per packet to damage cellular bonds, regardless of how dim the light is
  • Increasing the brightness of red light only adds more low-energy packets, never making any single packet stronger
  • Electrons sit at fixed, specific energy rungs within an atom rather than anywhere in between
  • Falling between specific rungs releases photons of exact colors unique to each element
  • Astronomers and chemists read these color lines like unique fingerprints or barcodes to identify elements
  • An incoming kick of energy pushes an electron up to an excited rung
  • The electron cannot stay excited indefinitely and drops back down
  • The drop immediately casts off the surplus energy as an emitted photon of light
  • Light travels and spreads out through space like continuous ripples
  • The instant light is absorbed or detected, it registers at an exact point as a discrete packet
  • Wave-particle duality means light acts like a wave in transit but a particle on impact
  • Accelerating charged particles continuously emit electromagnetic radiation under classical physics
