Zooming in The world is made of molecules Molecules are made of atoms

Atom Atoms are real Sodium chloride crystal lattice Atoms are small

Atoms have tiny masses Proton (charge 1+): mp = 1.672 x 10-27 kg Neutron (charge 0): mn = 1.674 x 10-27 kg Electron (charge 1-): me = 9.109 x 10-31 kg Why the Atom stays together r + – Coulomb potential The World of Atoms Atoms are extremely small Protons, neutrons in addition to electrons are extremely light Electrons are confined to the vicinity of the nucleus How do electrons move around the atom

What Newton predicts Motion of object can be precisely calculated from a set of observables: x – position of object v – velocity of object E – energy of object What Schrödinger says Position, v in addition to E of very small object can not have any r in addition to om value. Observables have only certain discrete values Who’s right White light passing through a prism produces a continuous spectrum. Hydrogen gas exposed to an electric discharge gives a line spectrum.

Who’s right Electrons are particles with a rest mass of me = 9.109 x 10-31 kg Do they also behave like waves Looks like the pattern that a wave would make! Who’s right Electrons confined to a circular well Schrödinger wins first prize! The world of atoms is described through Quantum Mechanics Electrons, protons, atoms have wave-like properties

Math tools Newton: Quantum: The shape of the wavefunction can be obtained from the Schrödinger equation: Wave properties The electron bound to the atom looks like a st in addition to ing wave.
