The fact that it is incredibly small. Also, the speed and location of a mass-less particle can not be known at the same time. Thus, electrons would be a problem.
Thomson is responsible for discovering that an atom contains electrons.
James chadwick was a scientist who made many contributions to the atom and he worked on various radioactivity problems. Sir James Chadwick has been given the credit for discovering the neutron.
Ernest Rutherford is credited with discovering the nucleus of the atom through his gold foil experiment in 1909. He observed that most of the particles passed through the foil, suggesting that the atom is mostly empty space with a concentrated positive charge at the center, which he called the nucleus.
Robert Millikan is credited with the discovery of the elementary electronic charge through his oil drop experiment.
Ernest Rutherford is credited with discovering the nucleus of an atom in 1911 during his famous gold foil experiment.
The plum pudding model suggested that the electrons were dispersed throughout the atom (like chocolate chips in a cookie) and the space was positively charged so that in the end the atom was neutral. Today, people know that the electrons are in a "cloud" around the atom and the protons (and neutrons) are in the nucleus, at the center of the atom.
Ernest Rutherford is credited with discovering that atoms are mostly comprised of empty space. Through his gold foil experiment in 1909, he showed that atoms have a dense, positively charged nucleus surrounded by mostly empty space where electrons orbit.
Japan had nothing left. Most soldier had died, and Japan abilities to feed the people or rebuild the country was null. It took 15 year for the US to rebuild the Japan again.
Chadwick won the Nobel Prize in Physics in 1935 for discovering the neutron, which is an uncharged atomic particle found in the nucleus of an atom. This discovery was crucial for advancing our understanding of atomic structure and the development of nuclear physics.

The oxidation state of one atom increases while another decreases.
An element refers to a type of atom, while atom refers to the specific one.Element can refer to many atoms, atom refers to the single particle.
