A proton has a mass of 1 AMU (one atomic mass unit)
A proton has a mass of approximately 1.67 x 10^-27 kilograms.
an electron is much lighter than a proton or neutron.
20 protons in calcium
If a proton, is a proton then it is a proton. (True).
About 1/1800.
No. While the proton has the opposite charge of the electron, the proton will not flow from atom to atom like the electron does because the strong atomic force holding the proton in the nucleus is much more powerful than the electromagnetic force.
A neutron has approximately the same mass as a proton. Electrons have much lower mass.
It would take about 1836 electrons to equal the mass of 1 proton. This is because the mass of an electron is much smaller than that of a proton.
The electron, because it has much less mass than the proton and momentum is the product of mass and speed.
yes much smaller
