John Dalton was known for his atomic theory.

His theory was that atoms form elements,

And that different elements would

Have atoms of different sizes and mass.

He believed atoms were unique, they

couldnt be created, destroyed by chemical


The later discovery of nuclear fusion and

Nuclear fission altered this view point,

Thouse these were nuclear and not chemical reactions

"It's the right idea, but not the right time."~John Dalton
