Democritus
Ernest Rutherford
J.J Thomson
“All substances are made of atoms, which cannot be created, divided or destroyed”
“Electrons travel around the nucleus in definite paths”
Current model -“There are regions inside the atom where electrons are likely to be found
called electron clouds”
Scientist
Atom Model
Theory
 Came up with the word ‘atom’
 All atoms are small, hard particles
that are “uncuttable” and always
moving
 Formed into different shapes and
sizes
 Ancient Greek philosopher
John Dalton
 Known for the “plum-pudding
model”
 Electrons are small, negatively
charged particles located throughout
the positive material of the atom
 Conducted the gold foil experiment
where positively charged particles
bounced back
 Proved the existence of the nucleus
 Most of the atom’s mass is in the
nucleus
