IDEA OF THE ATOM
The 5 main points of Dalton’s atomic theory:• Elements = particles called atoms• Atoms in same element are the
same; Atoms in different elements are different
• Atoms cant be destroyed/created• Atoms combine in elements
compound • chemical reactions=combined,
separated or rearranged
JOHN DALTON
• He was born on September 6th 1766 and he died on July 27th 1844 at the age of 78
• chemist, meteorologist and physicist
• modern atomic theory• Quaker family in Eagles
field• older brother named
Jonathan• He was colour-blind
• He was a chemist and a physicist
• Famous for atomic theory of matter
• elements = atoms = indestructible
• 1 of the fathers of modern physical
EXPERIMENTS/AREA OF STUDY
• famous for research on relativity of atom hydrogen
• book called “A New System of Chemical Philosophy”. atomic weights
• Daltonism = paper on colourblindness• Discovered butylene (alternative name for butene
(C4 H8) and he determined the • determined the composition of ether
