An electron is 1/1,836 of a proton.
Protons have a larger mass, but it is unclear which (if either) have a larger radius. The electron does not seem to have ANY measurable radius.
In kilograms, an electron's mass is ~9 x 10^(-31). A proton's mass is ~1.7 x 10^(-27). The mass of the proton is more than 1000 times of an electron.
Yes it is.
yes much smaller
Electrons are smallest
I believe it is reversed with a electron being smaller its mass is 1/1840 or 0.05% of a proton's. In fact the mass is so small we ignore it in calculation in stiochiometry. See here: http://www.physicsforums.com/archive/index.php/t-72615.html
You mean; " which sub atomic particle is almost 2000 times smaller than a proton? "An electron=========
an electron is much much smaller than an atom. An electron is a portion of the nucleus in an atom.
Actually every proton has different size in different nucleus. But in general, Proton, 1x10-15 m or "a diameter of approximately one-millionth of a nanometer". The electron, the diameter is less than 1x10-18 m. Likewise, The diameter of an electron is less than 1/1000 the diameter of a proton.
Compared to the (charge/mass) ratio of the electron:-- The (charge/mass) ratio of the proton is much smaller; although the proton charge is equal to the electron charge, the proton mass is much larger, by a factor of more than 1,800.-- The (charge/mass) ratio of the neutron is zero, because the neutron charge is zero.
The masses of all three particles are different The masses of a proton and the mass of a neutron are very close, however. The mass of an electron is much smaller than the mass of a proton or neutron.
A proton is bigger than electron
