The Structure of the Atom

First came Thales,
who thought the world rose from water
But then came Anaximenes, thinking along different lanes.
thought the world rose from air.

Democritus arrived later,
went on to say about atoms,
other philosophers thought this theory  wasn't better,
because a world made from tiny balls was something they couldn't fathom.

The common era arrived
and with it a blast of new scientists
such as Lavoisier, Proust and Dalton
who in their work were the finest.

Lavoisier set the law of conservation of mass
and Proust the low of definite proportion.
Dalton came up with the atomic theory,
and with this the three made history.

Bright and erudite, the 70s dawned,
JJ Thomson, Rutherford and Bohr were born.
in chemistry, these three were fond
for they made a discovery in which the three sciences could be bond.

JJ Thomson discovered the negatively charges electrons
and made the plum pudding model of an atom
But many thought he went in the wrong direction
As Rutherford proved JJ's theory's problems

Ernest Rutherford did the gold foil experiment,
fired alpha particles at atoms of gold,
they passed straight thought the atoms of the element
from this, the basic structure of the atom was mould.

Thought the structure seemed right, 
it raised questions about it's stability
Bohr came into the light and said,
"the atom has discrete orbits" sensibly.
