When Dalton's theory is it possible to convert atoms of the one element into atoms of another?
No, according to Dalton's theory, atoms of one element cannot be converted into atoms of another. Atoms are indivisible and cannot be created or destroyed in a chemical reaction. This concept is known as the conservation of matter.
What aspect of Dalton's theory was not supported by Thomsons findings?
Dalton's theory proposed that atoms are indivisible and have no subatomic particles, which was not supported by Thomson's discovery of the electron. Thomson's findings showed that atoms contain subatomic particles, challenging the notion of indivisible atoms in Dalton's theory.

Dalton. Dalton's atomic theory stated that atoms are indivisible and indestructible and unchangeable.

Why was Dalton's contribution different from that of the ancient Greeks Philosophers?
