What was discovery?
His MAJOR discovery was when he discovered the atom.
Alpha particles led to what discovery of what?
discovery of the atom's structure
How did thompsons cathode ray experiment change the atomic model of the day?
Thompson's cathode ray experiment led to the discovery of the electron, which was a fundamental particle in the atom. This challenged the earlier model of the atom as a solid, indivisible sphere by proposing a structure of a positively charged sphere with negatively charged electrons embedded within it. Thompson's model contributed to the development of the modern atomic model.
How did the discovery of the noble gases contribute to today's understandings of the structure of the atom?
Noble gases explain the stable behavior of any element and hence enhances the concept of atom's structure.
What did chadwhicks experiment kead to the discovery of?
Chadwick's experiment led to the discovery of the neutron, which is a subatomic particle with no charge located in the nucleus of an atom. This discovery helped to further our understanding of atomic structure and the composition of matter.
Rutherford's experiments led to the discovery of the?
Rutherford's experiments led to the discovery of the atomic nucleus. Through his gold foil experiment, he found that atoms have a small, dense, positively charged nucleus at their center and that the rest of the atom is mostly empty space. This discovery revolutionized our understanding of atomic structure.
Scientist who discovered structure of atom?
The structure of the atom was discovered by Ernest Rutherford and Niels Bohr. Rutherford's gold foil experiment led to the discovery of the nucleus, while Bohr proposed the planetary model of the atom with electrons orbiting the nucleus in specific energy levels.
How did thompsons experiment change daltons atomic model?
thomas discovered that the atom contained smaller particals called electrons
What evidence did J.J Thomson provided about this structure of an atom?
J.J. Thomson provided evidence about the structure of an atom through his discovery of the electron using cathode ray tubes. His experiments showed that electrons are negatively charged particles and are present in all atoms, leading to the development of the plum pudding model of the atom.
What is a model of the atom?
A model of the atom is a 3-D structure of the atom's structure.
Who are the scientist that historical development of an atom and their contribitions?
Some key scientists in the historical development of the atom include Democritus (concept of "atomos"), John Dalton (atomic theory), J.J. Thomson (discovery of the electron), Ernest Rutherford (discovery of the nucleus), and Niels Bohr (Bohr model of the atom). Each of these scientists made significant contributions to our understanding of the atom and its structure.
Who invented the proton?
Ernest Rutherford is generally credited with the discovery of the proton
