Who are the scientist who contributed in discovering atom?
The English chemist John Dalton (1766–1844) did much of this work, with significant contributions by the Italian physicist Amedeo Avogadro (1776–1856). It was Avogadro who developed the idea of a fixed number of atoms and molecules in a mole, and this special number is called Avogadro’s number in his honor.

Who is the father of atom?
John Dalton at times was known as the father of modern atomic theory. In 1803, he speculated that all atoms of a given element are identical in size and mass. Dalton; John Dalton reasoned that elements were composed of smaller atoms.
Who first discovered the atom?
The idea that everything is made of atoms was pioneered by John Dalton (1766-1844) in a book he published in 1808. He is sometimes called the “father” of atomic theory, but judging from this photo on the right “grandfather” might be a better term.
Who found atom first?
Although the concept of the atom dates back to the ideas of Democritus, the English meteorologist and chemist John Dalton formulated the first modern description of it as the fundamental building block of chemical structures.
How was the first atom created?
Atoms were created after the Big Bang 13.7 billion years ago. As the hot, dense new universe cooled, conditions became suitable for quarks and electrons to form. It took 380,000 years for the universe to cool enough to slow down the electrons so that the nuclei could capture them to form the first atoms.
