What else can I help you with?
Based on the data gathered in Millikan's oil-drop experiments the concept of atomic structure was modified Which of the following aspects of the structure of atom was validated by these experiment?
Millikan's oil-drop experiments validated the existence of discrete, quantized electrical charges on particles within the atom. This supported the idea proposed by Thomson that electrons are fundamental particles with a specific charge.
The scattering of light by colloidal particles?
This is because there are solid particles suspended in the mixture although it is more stable than a suspension.
What did J. J. Thomsons experiments provided evidence about an atom?
J. J. Thomson's experiments provided evidence for the existence of electrons as subatomic particles within the atom. This led to the plum pudding model of the atom, where electrons were embedded in a positively charged "pudding." These experiments laid the foundation for our understanding of atomic structure.
What scientific inquiry skill was Rutherford using in selecting Thomson's model for investigation?
Rutherford was using the scientific inquiry skill of hypothesis testing when selecting Thomson's model for investigation. He proposed an alternative model to test and refine the existing understanding of the structure of the atom, setting up experiments to gather evidence that would support or refute Thomson's model.
Who was milikan?
A scientist who made an expirament that was better then rutherfords expirament his was more avanced becuase with milikan's expirament you could study one drop at a time but rutherfords expirament requird you to study the whole cloud and by stuying the drop you could figure more out about the substance.
The proton in Rutherfords experiments were used to?
The proton in Rutherford's experiments were used as projectiles to bombard thin metal foils (such as gold) in order to study the structure of atoms. By observing how the protons scattered off the foil, Rutherford was able to deduce that atoms have a nucleus, which is small, dense, and positively charged.
What has the author D I Svergun written?
D. I. Svergun has written: 'Structure analysis by small-angle x-ray and neutron scattering' -- subject(s): Matter, Neutrons, Scattering, Small-angle scattering, Structure, X-rays
Who has performed the experiments to find out structure of an atom?
Rutherford
A method of determining the crystal structure of a material is?
Determining the x-ray scattering pattern of the crystal.
How did the atomic model evolve from indirect evidence?
The atomic model evolved from indirect evidence through various experiments like the cathode ray tube, the oil drop experiment, and the Rutherford scattering experiment. These experiments provided insights into the structure of the atom, leading to the development of atomic models such as the plum pudding model, the nuclear model, and eventually the modern quantum mechanical model.
What are the differences between Raman scattering and Rayleigh scattering?
Raman scattering and Rayleigh scattering are both types of light scattering, but they differ in how they interact with molecules. Rayleigh scattering occurs when light interacts with particles smaller than the wavelength of light, causing the light to scatter in all directions. Raman scattering, on the other hand, involves a change in the energy of the scattered light due to interactions with molecular vibrations. This results in a shift in the wavelength of the scattered light, providing information about the molecular structure of the material.
What did Thompson's experiments lead too?
Sir thompson did a huge service. His experiments led us to correct atomic structure.
What has the author John M Kalish written?
John M. Kalish has written: 'The biological and acoustical structure of sound scattering layers in the ocean off Oregon' -- subject(s): Echo scattering layers
Who did the alpha particle scattering experiment?
The alpha particle scattering experiment was conducted by Ernest Rutherford and his team in 1909 at the University of Manchester. This experiment led to the discovery of the atomic nucleus and revolutionized our understanding of the structure of the atom.
Why Rutherford does not use beta particles for scattering on gold foil?
Rutherford did not use beta particles for scattering experiments on gold foil because beta particles, being charged electrons, would have been deflected significantly by the electric fields of the atomic nuclei. Instead, he used alpha particles, which are positively charged and much heavier, allowing for a more straightforward interpretation of their scattering patterns. The interactions of alpha particles with the gold foil provided clearer insights into the structure of the atom, leading to the discovery of the nucleus. Additionally, alpha particles have a higher energy, which enhances their ability to penetrate the foil.
Why does water have not raman scattering?
Water does have Raman scattering, but it is relatively weaker compared to other materials due to its symmetric molecular structure and low Raman cross-section. This makes it more challenging to detect and study using Raman spectroscopy.
What is incoherent scattering?
Incoherent scatteringis a type of scattering phenomenon in physics. The term is most commonly used when referring to the scattering of an electromagnetic wave (usually light or radio frequency) by random fluctuations in a gas of particles (most often electrons).
