experminted with cathod ray tubes
used plum pudding or the coclete chip cokkies -
came up with the bohr model
the bohr model is a model where the lowest energy electrons are closer to the nucleus -
he came up with the broglie formula
which shows the relationship between mass volume and wave length -
came up with the uncertainty principle
which is that you can never tell where an electron will be
