The Atom

Experiments continued extensively to study the atom. In 1897 AD, the scientist Thompson discovered the negatively charged electron, which led to a radical change in previous beliefs. Thompson also concluded that the atom is electrically neutral, solid, and positively charged, and is interspersed with negative electrons. This model was named after him, which contributed to a broad new understanding of the atom. In 1911 AD, the scientist presented Rutherford developed the nuclear model of the atom and proved the existence of the nucleus.Since the atom is the building unit of the universe, it was and still is a matter that preoccupies scientists until now. Therefore, many scientists went to study it and created models that explain how the atom is built and its components? This book, written by Sir George Paget Thomson, seeks to answer some of these questions. It was first published in 1930 AD and the second edition was published in 1937 AD. The third in 1946 AD; And the fourth in 1954 AD, so enjoy this treasure in your hands, as it is a scientific legacy that explains the history of the atom in detail.
