When calculating an atomic approximate mass how is the mass of electron figured?
When calculating the atomic mass of an atom, the mass of an electron is typically considered negligible. This is because the mass of an electron is almost 2000 times smaller than the mass of a proton or neutron, which are the primary components used in determining the atomic mass of an atom.
Which scientist furthered knowledge of the electron by determining its charge and mass using an oil-drop experiment in 1909?
Robert Millikan
Why is the mass of an electron not used in determining the mass of an atom?
The mass of the electron is just so small compared to the mass of the protons and neutrons that it will not change it. Therefore the mass of the electron can safely be ignored.
What does the atomic mass of an electron represent?
The mass of an electron is atomic mass units is 5,485 799 090 70(16); the mass of the electron is not an atomic mass.
What is an electron's atomic mass number?
The electron has no atomic mass number. The mass of an electron is roughly 1/1800 of the mass of a proton or neutron.
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.
What important historical events happened in jj thomas life?
i think its historica enough for him that he is being remembered for determining the charge to mass ratio e/m of electron that also proved helpful for the determinition of mass of electron,
Explain why the electron isn't considered when determining the mass of an atom?
because the electron has such a tiny ity bity mass that it adds almost nothing to the atomic mass!
When determining the mass of an atom the electron are not considered why can scientists disregard the electrons?
Scientists can disregard the mass of electrons when determining the mass of an atom because the mass of electrons is significantly smaller than the mass of protons and neutrons. Therefore, the mass of electrons has a negligible impact on the overall mass of an atom.
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+
When calculating an atomic approximate mass how is the mass of electron figured?

What is the most important determining he fate of a star?
It is the mass of the star.
Which scientist furthered knowledge of the electron by determining its charge and mass using an oil-drop experiment in 1909?
Robert Millikan
Why do you measure mass in a science lab?
Measuring mass in a science lab is important for determining the amount of matter in a sample. Mass is a fundamental property of matter and is used in various calculations and experiments in chemistry, physics, and biology. It helps scientists understand the characteristics and behavior of substances.
Protons are so much more massive than electrons that you can neglect the mass of electrons when determining the mass of an atom?
Atomic mass is based on the proton and neutron. For the most part the mass of an electron is infinitesimally small.
Why is the mass of an electron not used in determining the mass of an atom?
The mass of the electron is just so small compared to the mass of the protons and neutrons that it will not change it. Therefore the mass of the electron can safely be ignored.
