What were the key developments in atomic theory?

Key developments include Dalton's atomic theory in the early 1800s, Thomson's discovery of the electron in 1897, Rutherford's gold foil experiment in 1909, and Bohr's model of the atom in 1913.

How did these theories change our understanding of matter?

These theories shifted our understanding from a continuous view of matter to a discrete particle view, leading to modern chemistry and physics.

What impact did atomic theory have on science and technology?

Atomic theory laid the groundwork for advancements in chemistry, physics, and even technology, including nuclear energy and medical imaging.
