Niels Bohr's discovery was primarily influenced by his work on atomic structure and quantum mechanics. He developed the Bohr model of the atom, proposing that electrons orbit the nucleus in specific energy levels. This model revolutionized our understanding of atomic dynamics and laid the foundation for modern quantum theory.
Experiments like the photoelectric effect and atomic emission spectra provided evidence that electrons exist in discrete energy levels. These findings challenged the classical model of the atom, leading to Niels Bohr proposing his model in 1913 to explain the quantization of electron energy levels in atoms.
The discovery of the atom is attributed to the work of multiple scientists throughout history, such as John Dalton, J.J. Thomson, Ernest Rutherford, and Niels Bohr. These scientists made significant contributions through their experiments and theories that led to our current understanding of the atom as the basic building block of matter.
Ernest Rutherford's experiments on the scattering of alpha particles by a thin sheet of gold foil led to the discovery of the atomic nucleus and the realization that atoms contain a central, positively charged nucleus called the proton.
Gregor Mendel studied the science of genetics, specifically through his experiments with pea plants that led to the discovery of fundamental laws of inheritance.
Yes, J.J. Thomson's experiments using cathode rays led to the discovery of the electron and the plum pudding model of the atom. This model suggested that atoms are not indivisible, but composed of smaller particles.

Yes, experiments with cathode ray tubes in the late 1800s, particularly by scientists like J.J. Thomson, led to the discovery of electrons. Thomson's experiments demonstrated that cathode rays were composed of negatively charged particles, which were later named electrons. This discovery laid the foundation for modern atomic theory.
Rutherford's experiments led to the discovery of the nucleus of an atom and the existence of protons within it. By conducting the famous gold foil experiment, Rutherford concluded that atoms have a small, dense, positively charged center containing protons.
J.J. Thomson's experiments with the cathode ray tube led to the discovery of the electron. This discovery revolutionized our understanding of the structure of the atom and laid the foundation for the development of modern atomic theory.
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.
Ivan Pavlov's experiments with dogs led to the discovery of classical conditioning, showing how learning occurs through association of stimuli. His research helped shift the focus of psychology towards understanding behavior and mental processes.
