Ch 5
the ground state of an atom or ion, electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels.
Aufbau
Electrons have -1
Orbiting ( moving ).
Outside the nucleus in the electron cloud.
Small ( 1840 electrons= mass of /proton/ neutron.
N1=2
N2=8
N3=18
N4=18
Hunds rule
Electrons spin opp. ways in an orbit.
Pauli's
1 or two electrons per orbit
Hesenbergs
Impossible to know the location and velocity of electron at the same time.
Neutral atom p+ = e-

Electrons orbit the nucleus like the planets orbit the sun.
It is possible to know the location and velocity of an electron at the same time.
Today's model: Electron cloud model.
The bigger the jump the more light is emitted..
low frequency= big wave lengths.
