Atomic Theory Timeline Song Words by Christy Johannesson To the tune of the “Alphabet Song”

Verse 1 Dalton’s model was the “Billiard Ball” Atoms are indivisible Thomson used the Cathode Ray Electrons are charged in a negative way His model was “Plum Pudding” Or a chocolate chip cookie

Verse 2 Becquerel found by accident Radiation from an atom went Oil drops were used by Millikan To find the mass and charge of an electron While they changed the models none They paved the way for others to come

Verse 3 Rutherford experimented with Gold Foil To find the nucleus he did toil Its positive charge and tiny size Showed that he was rather wise Electrons moving ‘round the nucleus Describes the “Nuclear Model” for us

Verse 4 Bohr said electrons move in orbits round In energy levels they can be found This explains the reason behind The bright-line spectrum that we find “Planetary Model” it was called But Bohr knew that it was flawed

Verse 5 The orbital proposed by Schrödinger Described most likely where electrons were Quantum mechanics was the new game “Electron Cloud” was the model’s name Finally Chadwick found the neutron But atomic theory still moves on
