You think probable to Leukipus and Democritus; and 2 300 years later John Dalton.
The first scientist to question the idea that atoms were indivisible was John Dalton, an English chemist, in the early 19th century. Dalton proposed that atoms were not actually indivisible, as previously believed, but rather could be rearranged in chemical reactions.
british scientist discovered the nucleus
Einstein was an atomic scientist inasmuch as he advanced the field of atom theory. His paper on "Brownian Motion" was one of the first to describe the free flowing motion of atoms in space. This question suffers from a question of intent. The short and long of it is yes, Einstein was a research theorthetical atomic scientist.

The scientist who first proposed that matter is made of atoms was John Dalton, in the early 19th century. Dalton developed atomic theory to explain chemical reactions and the behavior of gases.
The first conscious being to ask a question or wonder.
Democritus, the ancient Greek philosopher, was the first scientist to propose the concept of atoms as the smallest particle in the universe. He believed that all matter was made up of indivisible and indestructible particles called atoms.
J.J. Thomson, in 1897, was the first scientist to show that atoms emit tiny negative particles, which we now know as electrons. This discovery led to the development of the plum pudding model of the atom.
The English scientist who first offered strong evidence that atoms exist was John Dalton. He proposed his atomic theory in the early 19th century, which laid the foundation for modern atomic theory and our understanding of the nature of matter.
This begs the question by assuming that it was invented by a scientist. Ask the question "who invented the light bulb" - you'll get a better answer.
Ernest Rutherford proved it with his famous gold foil experiment.
