One view of atomic structure in early 20th
century was that an electron (e-) traveled
about the nucleus in an orbit.

Atomic Spectra and Bohr
Bohr said classical view is wrong.
Need a new theory — now called
QUANTUM or WAVE MECHANICS.
e- can only exist in certain discrete

energy state (quanta = bundles of
energy) 21 Quantum or Wave Mechanics
Schrodinger applied idea of eSchrodinger
behaving as a wave to the
problem of electrons in atoms.
He developed the WAVE
Solution gives set of math
expressions called WAVE
Each describes an allowed energy
state of an estate He...
