How can atoms make all of the substances around you?
Atoms can join together to form molecules, which in turn form most of the objects around you. Atoms are composed of particles called protons, electrons and neutrons. Protons carry a positive electrical charge, electrons carry a negative electrical charge and neutrons carry no electrical charge at all.
Is it true that according to current atomic theory electrons are in fixed locations?
According to current atomic theory, electrons are in fixed locations. Every atom of the same element has the same atomic number.
Who said electrons travel in definite paths?
Bohr
Who said electrons are scattered around the nucleus at a distance?
Niels Bohr
Who said that atoms are Uncuttable?
Democritus
Why are atoms Uncuttable?
The word atom is derived from the ancient Greek adjective atomos, meaning “uncuttable” or “indivisible.” The earliest concepts of the nature of the atom were debated in ancient India and ancient Greece.
Are all atoms Uncuttable?
Atoms are too small to see, “uncuttable,” and indestructible. All atoms of a given element are exactly alike and atoms of different elements are different. In 1897, the English scientist named J.J. Thomson provided the first hint that an atom is made of even smaller particles.
What was the main drawback of this model?
The drawback of Rutherford model is: It can’t explain the stability of an atom. As per the model, the orbital revolution of electrons around the nucleus is not stable as the revolving electrons in orbits will undergo acceleration and emit energy.
What was the purpose of Rutherford’s scattering experiment?
Rutherford scattering is the elastic scattering of charged particles by the Coulomb interaction. It is a physical phenomenon explained by Ernest Rutherford in 1911 that led to the development of the planetary Rutherford model of the atom and eventually the Bohr model.
What are the conclusion of Rutherford’s alpha particle scattering experiment?
Conclusion of Rutherford’s scattering experiment: Most of the space inside the atom is empty because most of the α-particles passed through the gold foil without getting deflected. Very few particles were deflected from their path, indicating that the positive charge of the atom occupies very little space.
What was the conclusion of Rutherford’s model?
Observation And Conclusion Of Rutherford’s Scattering Experiment
| Observations | Conclusion |
|---|---|
| Few particles bounce off the nucleus | Indicates that all the positive charge and mass of the gold atom were concentrated in a very small volume within the atom. |
Which of the following is an incorrect statement in reference with observation in Rutherford’s α par?
The only wrong statement is (c), as we cannot cite any reasons why a particle would not be able to pass through such a thin foil. Rutherford has also not observed anything like this in his experiment.
What are alpha rays give examples?
Examples of this sort of nuclear transmutation by alpha decay are the decay of uranium to thorium, and that of radium to radon. Alpha particles are commonly emitted by all of the larger radioactive nuclei such as uranium, thorium, actinium, and radium, as well as the transuranic elements.
