Question

compare the proton, the electron, and the nucleus in terms of location in the atom, mass and relative harge.

Answer 1

First, I think you are trying to type "charge", not "harge"

Now come back to your question. The nucleus is at the center of atoms and consists of protons and neutrons. The size of a nucleus is small compared to that of an atom. Let's make an analogy: if an atom is as big as the Earth, then one proton would only be as big as a ping-pong ball.

Protons are positively charge ( having a charge of 1) while neutron, as it's name suggests, is neutral ( having a charge of 0). they are almost the same in terms of size and mass. However, mass of protons, neutrons as well as electrons cannot be determined precise;y due to Quantum Physics theories. It is estimated that the mass of an electron is approximately 1/1864 of that of a proton. Electrons are negatively charged ( having a charge of -1) . They are located outside of the nucleus and flying around in "orbitals"

Answer 2

Well protons and neutrons are in the center in the atom, while electrons travel in orbitals outside of the nucleus. The electric charge for protons, neutrons, and electrons are 1, 0, and -1 respectively. the mass for protons and neutrons are 1 amu (atomic mass unit) while the electron is 1/2000 amu.
