the ground state of an atom or ion, electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels.
Electrons have -1
Orbiting ( moving ).
1 or two electrons per orbit
Electrons spin opp. ways in an orbit.
Impossible to know the location and velocity of electron at the same time.
Outside the nucleus in the electron cloud.
Small ( 1840 electrons= mass of /proton/ neutron.
It is possible to know the location and velocity of an electron at the same time.
The bigger the jump the more light is emitted..
low frequency= big wave lengths.
Electrons orbit the nucleus like the planets orbit the sun.
