Explanation: Both the Bohr model and the Rutherford The model that best represents atomic theory after Rutherford's discoveries is the planetary model, which describes atoms as having a dense nucleus surrounded by orbiting electrons. id. J. The differences between Rutherford's and Bohr's models are well-documented in atomic physics, particularly in how Bohr successfully explained the atomic spectra of hydrogen using his quantization principles, while Rutherford's model failed to address similar observations. What is The Rutherford model was devised by the New Zealand-born physicist Ernest Rutherford to describe an atom. This model depicted the atom as having a central nucleus made of protons and neutrons, with electrons moving in circular orbits around the nucleus at specific distances. This model was proposed on the basis of alpha particle According to Rutherford model, an atom consists of positively charged particles concentrated at the center known as the nucleus. J. Explanation: Rutherford's Impact on Atomic Theory. He bombarded radiation from a source on an atom. Who was Ernest Rutherford? Ernest Rutherford was a British physicist who remarkably discovered the atomic nucleus first The statement that correctly describes Rutherford's model of the atom is that the atom is mostly empty space. This means that the atom is highly unstable. Brainly Tutor. This statement is false. Rutherford's classical atom model could not explain the atomic structure since the atom was unstable due to the orbiting electron's constant emission of energy. *Electron Spin Describe Rutherford's model of an atom. The models of Rutherford and Bohr are instrumental in demonstrating the evolution of atomic theory, marking significant milestones in our understanding of the Before Rutherford's Planetary Model, the widely accepted model was J. Rutherford's model reshaped atomic theory by introducing a nucleus at the center of the atom, surrounded by orbiting electrons, based on his gold foil experiment results. He also claimed that the electrons surrounding the nucleus revolve around it with very high speed in circular paths. The → On the basis of the above observations, Rutherford gave some :- * As most of the alpha-particles passed through foil undeflected, it means most of the space of the gold atom is empty. The atom's positive charge is located in the atom's nucleus. Explanation: If Rutherford's idea that electrons radiate energy while orbiting around the nucleus was true, it would strengthen Bohr's model of the atom. Demerits of Rutherford's atomic model : 1.

Explanation: The Bohr model expanded on Rutherford's model of the atom by introducing the concept of quantized energy levels and electron orbits. So, the atom as a whole is electrically neutral. but in Click here 👆 to get an answer to your question ️ explain Rutherford's model of atom Brainly User Brainly User 05. In this model, the atom is depicted as having a tiny, dense, positively charged nucleus, around which the lighter, negatively charged electrons orbit much like planets around the sun. Thomson, which inaccurately The Rutherford model of the atom, proposed by Ernest Rutherford in 1911, depicted the atom as consisting of a small, dense nucleus that contains positively charged protons and neutral neutrons, surrounded by negatively charged electrons orbiting in set paths, similar to a mini solar system. In his experiments, Rutherford discovered that most alpha particles passed through a thin gold foil without any significant scattering. From the data he also calculated that the radius of the nucleus is about 105 times less than the radius of the atom. Rutherford's atomic model has a few drawbacks, including: Stability of electrons: Rutherford's model states that electrons revolve around the nucleus in a circular path. What is an atom? The atom consists of matter that may be split without releasing electrical charges. Final Answer. The Rutherford model is a model of the atom we know today. 04. Ezekiel2holloway. In 1913, Bohr introduced what is known as the Bohr model of the atom. This model was based on Rutherford's famous gold foil experiment, which demonstrated that atoms have a small, dense Final answer: Schrödinger is the scientist most responsible for the quantum mechanical model of the atom.
