The first person to develop the first model of the atom in 1803 was John Dalton.
The first widely recognized atomic theory was proposed by John Dalton in the early 19th century. Dalton's atomic theory suggested that all matter is made up of small, indivisible particles called atoms. This theory laid the foundation for modern chemistry.
In the following order: Heliocentric theory of the solar system (Aristarchus of Samos, 270 BCE) Natural Selection (Darwinian evolution, 1858) Theory of the hydrogen atom (as a small negatively charged particle inside a larger positively charged particle, 1904, the plum pudding model) Theory of relativity (special relativity, 1905) Theory of relativity (general relativity's initial paper on the acceleration of objects within the framework of special relativity, 1907) Theory of the hydrogen atom (as a small particle orbiting the atomic nucleus, 1909, the Rutherford or Planetary model) Theory of the hydrogen atom (as an "electron cloud" surrounding the atomic nucleus, 1913, the quantum mechanical or Bohr model) Theory of relativity (general relativity and its ability to warp space-time, 1915) So heliocentrism was, by about two millenia, the first. Relativity and the model of the hydrogen atom are intricately intertwined, so which came first depends on what you mean specifically.

Two scientists came up with The Cell Theory. It was in 1839, Matthias Schleidan and Theodor Schwann, two German Biologists came up with this theory.
No. Cell theory is the theory that cells make up organisms. The only theory dealing with the origin of life is life origin theory.
democritus was greek philosophers.
He invented atomic power He came up with the theory of Relativity. He came up with the theory of Gravity. He had all these equations like E=mc2
he came up with the theory of atomic numbers

atoms combine in whole numbers.
I don't know of atomic theory, but he came up with the idea that light energy acted like packetts of energy that he called photons. Thru some theoretical calculations he came up with Plank's constant that deals with the energy of different wavelengths of light.
The pre-modern idea of atomic theory was proposed by Greek thinkers like Democritus, Leucippus, and the Epicureans, which would have been at about 500 to 300 BC.
John Dalton, a pioneer in developing atomic theory, came from England. He was born in Eaglesfield, in Cumberland, England and later moved to Manchester.
This quote is attributed to British physicist and chemist John Dalton, who proposed the atomic theory of matter in the early 19th century. Dalton's theory stated that all atoms of a given element are identical and have specific characteristics that differentiate them from atoms of other elements.
He went to explore it in 1805 and just once he came back he got sent to another expedition in 1806. So he was on his exploration from 1805 to 1806.

He came up with the theory.
