Why does an electron have mass but does not have an diameter?
It has no diameter because it is a point particle (it has nothing inside it). It has mass because the mass has been measured experimentally. If this is hard to imagine, science has lots more concepts even harder.
How is mass measured in science?
it is measured by a vertex
Is mass and weight mesured in kg?
No. Mass is measured in kilograms. Weight is measured in Newtons.
What is the atomic mass of an electron?
an electron is about 1/1836 amu.
What is the formula for tons per hour?
Mass divided by time, where the mass is measured in tons and the time is measured in hours. If the mass and time are measured in other units they will need to be converted to tons and hours.
How do you find the relative uncertainty in the mass of the electron?
To find the relative uncertainty in the mass of the electron, you would typically determine the absolute uncertainty in the measurement of the electron's mass and then divide it by the measured value of the electron's mass. Finally, multiplying by 100 will give you the relative uncertainty as a percentage.
Why is the mass of electron difficult to find?
The mass of an electron is difficult to find because of the Heisenberg Uncertainty Principle. Either a particle's position or direction can be known, and the more precisely one is measured, the other is subject to more possible variation.
How can an electron have mass but no diameter?
It has no diameter because it is a point particle (it has nothing inside it). It has mass because the mass has been measured experimentally. If this is hard to imagine, science has lots more concepts even harder.

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 measured mass of hydrogen compare with its nuclear mass due to one proton?
The mass of the whole hydrogen atom includes the mass of an electron as well as the proton. The proton mass is nearly 2000 (actually about 1836) times greater than the electron mass. So, the mass of the hydrogen atom isn't much different from the mass of the proton. It's also possible this question could be about isotopes. Hydrogen has rare isotopes with one or two neutrons in the nucleus. So, the average mass of hydrogen, as measured, is usually a bit more than you would expect from just a proton and electron. However, these other isotopes are very rare and the effect on the mass of a sample of hydrogen would be very small.
What are the units for mass defect?
The units for mass defect are atomic mass units (amu) or kilograms (kg). It represents the difference between the sum of the masses of individual nucleons within an atom and the actual measured mass of the nucleus.
What unit is the mass of a plane measured in?
Mass is measured in kilograms.
Which subatomic particle has the smallest mass alpha particle neutron electron proton?
among these Electron has the least mass....
When J J Thomson discovered the electron what physical property of the electron did he measure?
Thomson measured the charge-to-mass ratio of the electron, which was found to be much smaller than that of any known atom. This suggested that the electron was a fundamental particle and not a substructure of an atom.
What is the mass of of an electron?
Electron has a mass of about 9.10938215 × 10−31 kg.
