john Dalton
Democritus contributed to the atomic theory around 400 BC. He proposed that all matter is composed of indivisible particles called atoms.
Democritus formulated his atomic theory in the 5th century B.C. He proposed that all matter is made up of tiny, indivisible particles called atoms. His ideas laid the foundation for modern atomic theory.
Democritus made his observations on atoms around 400 BC. He proposed that all matter is made up of indivisible particles called atoms, which he believed were constantly in motion. These ideas laid the foundation for the modern atomic theory.
The idea that the world is made up of atoms was proposed by the ancient Greek philosopher, Democritus, around 400 BC. He suggested that all matter is composed of tiny, indivisible particles called atoms that are constantly in motion. This atomic theory laid the foundation for modern chemistry.
The concept of atoms was proposed by the Greek philosopher Democritus around 400 BCE. However, the modern atomic theory was developed by John Dalton in the early 19th century, which expanded on the idea of atoms as indivisible particles that make up all matter.
I am almost sure it was Dalton but I may be wrong

The concept of an atom was first proposed by Democritus in the 5th century BCE. But he was ignored until the start of the 19th century that an English chemist named John Dalton again proposed it.
Albert Einstein It was not discovered as it did not then exist, we had to invent it ourselves. It was actually Max Planck and others who 'quantized' matter, and even light, after Newton and Boscovitch.
The concept of atoms was proposed by the Greek philosopher Democritus around 400 BCE. However, the modern atomic theory was developed by John Dalton in the early 19th century, which expanded on the idea of atoms as indivisible particles that make up all matter.
Democritus, an ancient Greek philosopher, is credited with championing the idea of the atom around 400 BC. He proposed that all matter is made up of tiny, indivisible particles called atoms, which come in different shapes and sizes. Though his ideas were not widely accepted at the time, they laid the foundation for modern atomic theory.
There are many different scientists responsible for the modernization of the atomic theory, but the first to actually describe them as atoms was Democritus and Leucippus in 5th Century BCE. For more information on the development of the atomic theory, look up these scientists (in no particular order): Dalton, Rutherford, Bohr, Chadwick, J.J. Thomson, and Mendeleev (he created the periodic table)
