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 is the atomic mass of an electron?
an electron is about 1/1836 amu.
What is the ratio of the mass proton to the mass of an ELECTRON?
Dunno, but the ratio of the mass of a proton to the mass of what prople think of as being an electron is approx 1980. I'd check that if I were you though. Probably OK to +- 5%.
How does the mass of a nucleus compare to a electron?
The mass of a neutron is approx 1837 times that of an electron. The mass of a proton is similar to that of a neutron. In the simplest atom, hydrogen, the mass of the nucleus is 1,837 times that of an electron. In the largest known atom, that of ununoctium, containing 281 baryons (neutrons or protons) the mass of the nucleus is approx 516,200 times that of an electron. So take your pick: 1,837 to 516,200.
Can you explain why the estimation of the diameter of an atom is greater or less than the known value?
Here's a guess... Without getting overly complicated.... The diameter of the atom isn't just the diameter of the atom's nucleus... it is the diameter of the whole atom including the electron cloud surrounding the nucleus. As the name implies, an electron cloud represents all the possible locations that the electron could be. This cloud has thickness and therefore the atom could be smaller if the electron is in a portion of the cloud closer to the nucleus or larger is the electron is in a portion of the cloud farther from the nucleus. The "known value" is probably just the average of the two. Therefore, an atom's diameter has a range rather than a fixed value.
What is Electron Relative mass?
it is usually the mass without the x10^-31
How can you measure the diameter of an electron if an electron has the mass of 9.10910to the -31kg?
An electron, being a point particle, by definition has a diameter of zero. This has no relation to its mass.
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.
How can 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.
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.
Who has the smallest mass electrons protons or neutrons?
Of the neutron, proton, and electron, the electron has the smallest mass.
The rest mass energy of an electron positron pair is?
Twice the mass of the electron, since the positron has the same mass of the electron. Or the equivalent, in energy units.An electron has a mass or energy of 511 keV.
What is the mass of of an electron?
Electron has a mass of about 9.10938215 × 10−31 kg.
How does the mass of an electron compared to the mass of proton?
The proton mass is about 2,000 times greater than the electron mass.
How does the mass of electron compare to the mass of the proton?
The proton mass is about 2,000 times greater than the electron mass.
How does the mass of an electron compare to the mass of proton?
The proton mass is about 2,000 times greater than the electron mass.
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.
