Who Made The Planetary Model

The Bohr model is a planetary model of the atom proposed by Danish physicist Niels Bohr in 1913. It describes the structure and spectra of hydrogen and hydrogen-like atoms based on quantum theory. What is the Bohr Model? The Bohr Model is a model of an atom.

The model was proposed by physicist Niels Bohr in 1913. In this model, the electrons travel around the nucleus of an atom in distinct circular orbits, or shells. The model is also referred to as the planetary model of an atom.

The nucleus represents the sun, and the electrons represent the planets orbiting around the nucleus. Unlike gravitational forces that keep planets in their orbits, electrons are held in their orbits by electrostatic forces. Thus, the Bohr model is often called the planetary model [1-4].

Niel Bohrs Atomic Theory states that an atom is like a planetary model where electrons were situated in discretely energized orbits. The atom would radiate a photon when an excited electron would jump down from a higher orbit to a lower orbit. This led the scientists to the conclusion that at the centre of the atom was a large positive mass and Rutherford suggested a planetary model where electrons moved around this central mass like the planets around the sun.

At this point, Rutherford and Marsden dusted off an unpopular and neglected model of the atom, in which all the electrons orbited around a small, positively charged core or "nucleus," just like the planets orbiting around the sun. Learn how Niels Bohr developed a quantitative model of the atom based on Rutherford's theory of a positively charged nucleus and negatively charged electrons in orbit. Find out how Bohr explained the emission of radiation by electrons jumping between orbits.

Rutherford's atomic model or planetary model of the atom is a model proposed by Ernest Rutherford. In 1909 the Geiger and Marsden experiment was performed, also known as the Rutherford experiment, as it was led by Rutherford himself. Who created the planetary model of the atom? in 1911, Ernest Rutherford discovered the nucleus of the atom and proposed the planetary model.

The planetary model said that the electrons moved around the nucleus like planets orbiting the sun, at random. Bohr's planetary model is a conceptual framework for understanding atomic structure, proposed by Niels Bohr in 1913. It depicts electrons orbiting the nucleus in fixed paths, similar to planets orbiting the sun, and introduced quantized energy levels that explain how atoms emit and absorb light.
