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.
What are the units for mass defect?
For an atom... ( proton mass * number of protons + neutron mass * number of neutrons + electron mass * number of electrons ) - mass of atom in neutral state = mass deficit
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.
What is mass measured on?
Mass is measured on anything it can be measured on so it cant be

What is the smallest whole particle on this planet?
The smallest particle is the muon neutrino. The subatomic particles are not measured in size; they are measured in energy. The muon neutrino has an energy of less than 0.170 MeV/c2.
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.
Who has the smallest mass electrons protons or neutrons?
Of the neutron, proton, and electron, the electron has the smallest mass.
What unit is the mass of a plane measured in?
Mass is measured in kilograms.
