Best Answer

Protons have a diameter of 1.6 to 1.7×10−15 meters.

The electron is known to be a point particle up to an upper limit of 10-18 m. It does not conventionally have a size. So it is impossible to compare the size of the proton to that of an electron.

The MASS of the electron is 1/1836 of the MASS of a proton. This does not however tell you anything about their relative dimensions.

It is difficult to compare the size of particles so small. Subatomic particles are not really like little balls. They exhibit particle properties but also wave properties. The electron shells around atoms are more like regions in space of differing probabilities that an electron will exist in a particular place. The electron can be considered as the size of this region. The best comparison is of their mass but even this is not strictly defined. The faster they move the greater their mass. Masses of such small particles are therefore quoted as a REST MASS which is the mass it would have if it was still and by itself unbound in an atom. The rest mass of a proton is 1.673 x 10-27 kilogram. This is 1,836 times larger than the rest mass of the electron.

yes they are the same size.


Is the number of protons the positive charge of an atom?

The charge of an atom depends on the electrons compared to protons. Electrons being negatively charged, protons being positive. If there are more protons, the atom is positive, and if there are more electrons, the atom is negative.


What effect does the charge of the atom have on the number of protons?

The number of protons compared to electrons is what determines the charge of the atom. If there are more protons than electrons the atom is positively charged. If there's more electrons than protons the atom is negatively charged. Does this answer your question?
