Question

Describe rutherford's experiment for demonstration or the structure of atom and write its inference

Answer 1

Rutherford's experiment demonstrates the structure of the atom.

• Rutherford's gold foil experiment shows that the atom is mostly empty space with a tiny, dense, positively-charged nucleus. Based on this experiment Rutherford proposed the nuclear model of an atom.

Rutherford's gold foil experiment.

• Rutherford took a very thin gold foil of 100nm thickness which he bombarded with alpha rays.
• Alpha rays are particles that are positively charged ions.

Observation of Rutherford's gold foil experiment.

• Rutherford observed that most of the alpha rays passed through the gold foil without going through any deviation.
• Some of the alpha rays show some deviation.
• And very few alpha radiations bounced back to their source.

Conclusion.

• Rutherford concluded that the major portion of the atom is hollow and does not carry any charge. Therefore most of the alpha rays passed through without deviation.
• Some of the alpha rays show slight deviation which infers the presence of a positively charged portion in an atom. The positive charge in an atom offers repulsive force on alpha particles.
• The very few alpha rays that bounced back show that the positively charged portion is of very small size compared to the size of the atom.

Answer 2

Answer:

Rutherford's experiment demonstrated the existence of a nuclear atom, which consists of a tiny, positively charged nucleus that is encircled by empty space, followed by an outer shell of electrons. Rutherford was not involved in the far later discovery of the protons and neutrons that make up the nucleus.

Explanation:

We know that electrons, protons, and neutrons make up the structure of an atom. After several models were developed by various scientists, this was properly stated.

Ernest Rutherford presented what is known as the Rutherford atomic model or Rutherford model of the atom, which is the traditional representation of an atom. It is no longer regarded as a true depiction of an atom, though.

According to Rutherford, an atom is primarily made up of empty space, with the electrons orbiting the positively charged nucleus in a regular, predictable pattern.

Based on that, he presented a model in which electrons were evenly implanted in a positively charged matrix. The plum pudding model was the model's nickname. However, there were several drawbacks. J.J. Thomson's plum pudding paradigm. Certain experimental findings pertaining to the atomic makeup of elements were left unexplained.

Rutherford's Model of Atoms, which was put out by British physicist "Ernest Rutherford," is a model of the atomic structure. In one experiment, he blasted -particles into a thin sheet of gold. In this experiment, he looked at the path that the -particles took after coming into contact with the thin sheet of gold.

Hence, Rutherford's experiment for demonstrating the structure of the atom and its inference is explained above.
