There were four scientists that discovered the atom. These scientist were John Dalton, William Crooke, J.J. Thomson and Ernest RuthThere were four scientists that discovered the atom. These scientist were John Dalton, William Crooke, J.J. Thomson and Ernest Rutherford.
the scientist behind the concept of the atom are joseph john thomson,goldstein, and james chadwick!
An atom consists of a sphere of positive charge with negatively charged electron embedded in it,The positive and the negative charges in an atom are equal in magnitude, due to which an atom is electrically neutral. It has no over all negative or positive charge.
He described the atom as a sea of positive charge sprinkled with electrons
He discovered that the atom contained smaller particles called electrons.
J.J. Thomson contributed significantly to our understanding of the atom through his discovery of the electron in 1897. By conducting experiments with cathode rays, he demonstrated that these rays were composed of negatively charged particles, which he termed "corpuscles," later known as electrons. This finding led to the realization that atoms are not indivisible but consist of smaller subatomic particles. Thomson's work paved the way for the development of the "plum pudding" model of the atom, which described a positively charged sphere with embedded electrons.
J. J. Thomson was an English physicist (1856-1940).
Thomson is responsible for discovering that an atom contains electrons.
J.J. Thomson's discovery of the electron in the late 19th century helped revolutionize our understanding of the atom. His experiments with cathode rays led to the development of the plum pudding model of the atom, which proposed that atoms contain negatively charged electrons embedded in a positively charged sphere. This model eventually paved the way for the modern understanding of atomic structure.
Scientists like JJ Thomson, Ernest Rutherford, and Niels Bohr were pioneers in advancing our understanding of the atom. Thomson discovered the electron and proposed the plum pudding model, Rutherford conducted the gold foil experiment leading to the discovery of the atomic nucleus, and Bohr introduced the idea of quantized electron energy levels and the planetary model of the atom. Together, their contributions laid the foundation for modern atomic theory and our understanding of the structure of atoms.
The atom research conducted by John Dalton, J.J. Thomson, Ernest Rutherford, and Niels Bohr contributed significantly to our understanding of the structure of the atom. Dalton proposed the atomic theory, Thomson discovered the electron, Rutherford formulated the nuclear model of the atom, and Bohr developed the planetary model of the atom. These discoveries paved the way for modern atomic theory and revolutionized our understanding of matter and chemical reactions.
J.J. Thomson discovered the electron and proposed the plum-pudding model for the atom.

JJ Thomson discovered electrons, which showed that atoms are not indivisible.
Joseph John Thomson or (JJ Thomson)
John Dalton, J.J. Thomson, Ernest Rutherford, Niels Bohr, and Erwin Schrödinger were all instrumental in the development of our understanding of the atom. Each of them made significant contributions to the atomic theory and the structure of the atom.
