What are the drawbacks of rutherford model of atom

According to the Bohr's model of an atom, 'while revolving in discrete orbits the electrons radiate energy'. Use app Login. Which of the statements are the drawbacks of Rutherford's model of an atom? The orbital revolution of the electron is not expected to be stable Any particle in a circular orbit would undergo a acceleration and the charged particles would radiate energy The revolving electron would lose energy and finally fall into the nucleus All of the above.

Rutherford atomic model was the first step in the evolution of the modern atomic model. Ernest Rutherford was a keen scientist who worked to understand the distribution of electrons in an atom. He performed an experiment using alpha particles and gold foil and made the following observations:. From these conclusions, he calculated that the radius of the nucleus is around 10 5 times less than that of the atom. Rutherford developed a nuclear model of the atom on the basis of his experiment and observations.

What are the drawbacks of rutherford model of atom

Rutherford Atomic model is also known as the Rutherford model, nuclear atom , or planetary model of the atom was established in the year which explained the structure of atoms and was developed by the New Zealand-born physicist Ernest Rutherford. The model derived that the atom is nothing but a small tiny dense mass that has a positively charged body present in the core which is presently known as the nucleus where the entire mass of the atom is concentrated and around it revolves the negatively charged light electrons at a certain distance much like the planets revolving around the sun. In the gold foil experiment, the nucleus was postulated as a dense and small mass which was responsible for the scattering of the alpha particles. It was observed in a series of experiments that were carried out by the undergraduate Ernest Marsden under the guidance of Rutherford and German physicist Hans Geiger in Thomson worked on the fact claimed by the plum-pudding atomic model that the electrons are embedded into the positively charged mass that was claimed as the atom-like plums in a pudding.

The trajectory of the alpha particles was then studied after they interacted with the gold foil. There was a radioactive source that emitted Alpha particles which are positively charged particles that were enclosed within a lead shield in a protective manner. The radiation then passed in a narrow beam after it passed through a slit which was made in the lead screen. A very thin section of a gold foil is placed before the lead screen and the LED screen was covered with zinc sulphide so as to give it a fluorescent nature that served as a counter detection to the Alpha particles. As soon as the Alpha particles right the fluorescent screen it's shattered into a burst of light which is known as scintillation. It was visible from the viewing microscope that was attached to the back of the screen.

But the discovery of subatomic particles such as muons, mesons, quarks, and other elementary particles disprove that. It can also be said that the electrons were embedded uniformly around the positively charged nucleus, and the force between the positive and the negative charges is what keeps an atom in place and intact.

At that time those hypotheses are considered revolutionary as there was an experiment to back that hypothesis. But as the experiment performed by Rutherford is rudimentary in nature, this model of the atom can be seen with a lot of major drawbacks, all of which we will be learning about under the heading Drawback. Many scientists came up with different ideas and explanations of the structure of an atom such as Thomsom and Bohr. The most classical and accurate model was introduced by the scientist named Ernest Rutherford in the year However, the model did give a brief introduction to what and how the atom is formed. Rutherford explained that an atom is mainly made up of Electrons negatively charged particles and nuclei positively charged particles , and they are arranged in the atom in a fixed manner.

Rutherford found this by bombarding a thin sheet of gold foil with alpha rays helium nuclei. He proved his statement with an experiment by bombarding a thin sheet of gold foil with alpha rays. When a-particles collide with the sulphide screen, they emit light flashes. Based on the above observation, the following conclusions are drawn:. The postulates are:. The Rutherford model of the atom states that the atom is made up of an atomic nucleus and electrons that surround it. Rutherford proposed this atomic model using the gold foil experiment which revealed that the center of the atom has a positively charged solid material, whereas the remainder of the atom contains more empty space and the solid positively charged material was assigned as the nucleus. He specified that electrons must revolve in orbits of definite size and energy. The energy of an electron is dependent on the size of the orbit; hence smaller orbits provide low energy. Only when an electron moves from one orbit to another can radiation occur.

The atomic model proposed by Ernest Rutherford was a significant milestone in the development of modern atomic theory. Rutherford's intense research focused on understanding the arrangement of electrons within an atom. He conducted an experiment utilizing alpha particles and gold foil, leading to these key observations:. From these conclusions, Rutherford deduced that the radius of the nucleus is approximately 10 5 times smaller than the radius of the atom. Based on his experiment and observations, Rutherford proposed a nuclear model of the atom. The key characteristics of Rutherford's atomic model are:. Despite its groundbreaking nature, Rutherford's atomic model faced scrutiny and criticism. The model fell short in explaining the stability of electrons moving in a circular path.
