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.
What type of charge do electrons have?
The charge of an electron is -1, and has a smaller mass of a proton. (For you Castle Learning users) :]negative chargeAn electron carries one fundamental unit of negative charge*, measured to be about 1.609 x 10-19 Coulombs.(* The negative designation is a convention, established in the earliest experiments with electricity long before the existence of the electron was known.)A proton has a +1 charge.A neutron does not have a charge, it is neutral.

What are the relative charges of proton neutron and electron?
Proton's have a positive charge, neutron'shave a neutral charge, electron's have a negative charge
What subatomic particle has a charge of -1?
The electron is a subatomic particle that has a charge of -1.
Who conducted experiments to determine the quantity of charge caried by an electron?
Robert A. Millikan conducted these experiments. His discoveries are instrumental to atomic and particle theory.
What did thomson's cathode ray tube experiments help scientists learn?
Thomson's cathode-ray tube experiments helped scientists learn about electrodes and that atoms were comprised of many small particles, which they did not know existed. They also learned from this tube that all the electrons were the same regardless of what elements they came from.
What did thomsons cathode-ray tube experiments help scientists learn?
Thomson's cathode-ray tube experiments helped scientists discover the existence of negatively charged particles, or electrons, and their fundamental role in the structure of atoms. This laid the foundation for the development of the atomic model and contributed to the field of particle physics.
The work of which two scientists was most important in determining the mass of an electron?
The work of J.J. Thomson and Robert Millikan was crucial in determining the mass of an electron. Thomson's experiments in 1897 led to the discovery of the electron, establishing its charge-to-mass ratio. Later, Millikan's oil drop experiment in 1909 allowed for the precise measurement of the electron's charge, which, when combined with Thomson's findings, enabled the calculation of the electron's mass. Their contributions laid the foundation for our understanding of atomic structure.
Millikan's oil drop experiment helped determine the mass of an electron by allowing scientists to measure which of these?
the charge carried by an electron A+
The work of which two scientists was most important in determining the mass of an eletron?
The work of J.J. Thomson and Robert Millikan was most important in determining the mass of an electron. Thomson discovered the electron's existence based on cathode ray experiments, while Millikan conducted the oil drop experiment to measure the charge of the electron and hence its mass.
The work of what two scientists was most important in determining the mass of an eletron?
The work of J. J. Thomson and Robert Andrews Millikan were most important in determining the mass of an electron. Thomson discovered the electron through his experiments on cathode rays, while Millikan conducted the oil drop experiment, which helped to calculate the charge and mass of the electron.

Why could the neutron not be discovered in same experiments as the electron and proton?
Early experiments were based off attraction. The neutron had no charge to attract or repel or to be attracted or repelled. so these experiments could not figure out that there was a neutral particle in the nucleus.
The experiment that revealed the charge of the electron involved the use of what?
Study of cathode rays by J. J. Thompson and co-workers in 1896.
