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.
How does the mass of a proton compared to the mass of the electron?
The proton mass is about 2,000 times greater than the electron mass.
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!
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+
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
What did thomsons cathode-ray tube experiments help scientists learn?
the ratio of mass to charge for an electron. A+
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.
What is the most important factor in determining a stars life cycle?
The most important factor is the stars mass.
When determining the mass of an atom the electron are not considered why can scientists disregard the electrons?
Usually they are measuring just the necleus of the atom since it would be a whole number. This is called finding the Mass number. The atomic weight is the whole atom together, which is a whole lot of decimals. So they take the atomic weight and round it to a whole number for the mass number. For example, Boron (an element on the table) has an atomic weight of 10.811. But scientists round the number upward to 11 to be the Mass number.
What is most important for determining the type of atmosphere a planet has?
mass of the planet and the distance from the sun
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 is smallest atom neutron electron or ion?
The electron has the least mass of the three mentioned. That's why the valance electrons are the determining factor in most reactions. The proton closely follows the neutron because they are exactly the same except for charge. This leaves the the electron as the lightest sub-atomic particle.
