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.

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.
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.
What do scientists use to measure the mass of the particles within an atom?
Scientists use a unit called atomic mass unit (amu) to measure the mass of particles within an atom. This unit is based on the mass of a proton or neutron, and it helps scientists compare the mass of different atoms accurately.
What do mass and volume have in common?
Mass and volume are both physical properties of matter that describe different aspects of an object. Mass is a measure of the amount of matter in an object, while volume is a measure of the amount of space that an object occupies. Both mass and volume are important in determining the density of an object, which is the mass-to-volume ratio.
How do you know which has a greater momentum?
The momentum of an object is determined by its mass and velocity. An object with greater mass or velocity will have a greater momentum. Momentum is a vector quantity, so both magnitude and direction are important in determining which object has a greater momentum.

What is the mass of eletron?
About 9.109 x 10-31 kg.
What is the most important determining he fate of a star?
It is the mass of the star.

What is most important for determining the type of atmosphere a planet has?
mass of the planet and the distance from the sun
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.
What is the most important factor in determining the path a star takes when it leaves the main sequence?
The main factor is its 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.
What is delivered by adding the number of protons with the number of neutrons?
Adding the number of protons and neutrons in an atom will give you the atomic mass of the atom. The atomic mass is important for determining the overall mass of the atom and is an important factor in chemical reactions and nuclear stability.
When determining the mass of your friend what do you use?
A mass balance.
What is the most important factor in determining a stars life cycle?
The most important factor in determining a star's life cycle is its mass. The mass of a star determines its size, temperature, and how it will evolve over time. More massive stars have shorter lives and end in a violent supernova explosion, while less massive stars like the Sun will eventually become a white dwarf.
What symbol do scientists use to represent atomic mass unit?
Scientists use the symbol "u" to represent atomic mass unit.
