Proton is a factor of 10^4 times the mass of an electron.
The number of protons and neutrons controls the weight of an atom.
The weight of an atom is primarily controlled by the total number of protons and neutrons in its nucleus. Protons and neutrons have approximately the same weight, while electrons have negligible mass compared to protons and neutrons.
The number of protons, neutrons and electrons.
The atomic number of an element is equal to the number of protons, which also equals the number of electrons in a neutral atom.
Find the atomic number. That tells you the number of protons and electrons (in a neutral atom). Then find the atomic weight. The number of protons plus the number of neutrons will equal the atomic weight. So if you know the wt. just subtract the number of protons and you will have the number of neutrons.
Both, while electrons make up the most of the shell that counts as volume for matter electrons still require protons to keep them in stable orbit. But in short yes it is the electrons. Alex PH

Protons and neutrons are about the same weight. Electrons are far lighter than either protons or electrons.

By their atomic weight..protons and electrons.
As I remember neutrons and protons weight something similar, electrons have a far smaller mass which is negligable in comparison to the weight of protons.
The number of protons, neutrons and electrons.
The atomic number is how many protons there are, and since the number of protons is equal to the number of electrons, it is also the number of electrons. You can take the number of protons away from the atomic weight (overall weight) which will give you the number of neutrons. (Electrons don't weigh anything in the atomic weight so you don't need to subtract this as well). Hope this helps :D

Protons are positively charged but are not the lightest. They are about 2000 times the weight of electrons.
The protons and neutrons, but not the electrons since they are about thousand times lighter than protons and neutrons.
