Why do scientists say that mostt of the mass of an atom is located in the nucleus?
The masses of protons and neutrons are on the order of 1x10-27 kg. The mass of an electron is on the order of 1x10-30 kg. So protons and neutrons, the particles found in a nucleus, weigh around 1000 times as much as the electrons outside the nucleus. So take helium-4 for example: 2 protons, 2 neutrons, and 2 electrons. Its nucleus is around 2000 times more massive than its two electrons. The term "concentrated" is also worth noting. Atoms are much, much, much bigger than their nuclei. A good analogy I often use for this is that if you put a penny in the middle of Giant's stadium, the atom would be the size of the stadium and the penny would be the size of a nucleus. A more specific example would be that the nucleus of a carbon atom has a radius of around 2x10-15 m, and the radius of a carbon atom is around 8x10-11 m. So the nucleus is 40,000 times smaller than the atom.

What is the subatomic particle located farthest from the nucleus of the atom?
The electron is the subatomic particle located farthest from the nucleus of the atom.
Which particals in an atom are in the neucleus?
Protons and neutrons are the particles that are located in the nucleus of an atom. Electrons are located outside the nucleus in electron shells.
Do protons orbit the nucleus in an atom?
No, protons do not orbit the nucleus in an atom. They are located within the nucleus along with neutrons. Electrons are the particles that orbit the nucleus in an atom.
