There are 3 parts to an atom:
1. Protons
2. Neutrons
3. Electrons
The electrons are the smallest of the 3 and therefor weigh the least.
A proton is composed of 2 up quarks and 1 down quark while a neutron is composed of 1 up quark and 2 down quarks.
The Up Quark weighs more than the Down quark. Therefore, the proton would weigh more.
See Photon exhange to see how an Up quark turns in a Down quark through photon exchange.
What else can I help you with?
What is the heavy particles of an atom?
proton
Where are the heavy particles of an atom found?
in the nucleus (composed of protons and neutrons).
What part of the atoms caused the particles to bounce?
The heavy, dense nucleus of the atom caused the alpha particles to bounce back in Rutherford's experiment.
What Rutherford believed that each atom has?
Rutherford performed a famous experiment where he fired alpha particles at very thin gold foil.The experiment was set up with detectors both in front and behind the gold foil. Alpha particles are relatively heavy but small particles, like a helium atom without electrons.Rutherford proved in this experiment that the atom consisted mainly of space (most of the alpha particles went through the gold foil) but with extremely dense nuclei (some of the alpha particles were deflected or even bounced back they way they had come).This was a leap forward in knowledge about the structure of the atom at the time. The atom wasn't a uniform structure with particles evenly distributed in it. Rutherford proved and believed that the atom had a heavy, dense nucleus with electrons relatively far away.
Are electrons the positively charged particles in an atom?
In an atom of antimatter, that would be true, in an atom of matter that would be false.
What are the names of the particles in the atom?
The 3 Particles in a atom are * Proton * Neutron * Electron
What difference between atom and subatomic?
thesubatomic particles are the particles smaller than an atom
Why does not a heavy atom eject electrons from its shells and instead emits alpha and beta particles?
The reason a heavy atom breaks apart is, precisely, because of an instability in its nucleus. Note that the forces within the nucleus are several orders of magnitude stronger than the forces between the nucleus and the electrons.
What are positively charged electric particles in an atom?
Protons are the only positively charged particles in an atom.
How does subatomic particles relate with the atom?
The atom contain subatomic particles as neutron, proton, electron.
What particles are with the protons in the nucleus of an atom of an atom?
neutrons
Where are the electrons of an atom called?
they are the negative particles in an atom
