proton
No. a neutron is a subatomic particle found in the nuclei of all atoms except for hydrogen-1.
The particle you are referring to is an "electron." It is a negatively charged subatomic particle found in atoms.
the electron
an electron is found in shells , it is a subatomic particle
Protons are similar to hydrogen ions because they are positively charged particles found in the nucleus of an atom. Hydrogen ions are just protons that are not associated with an electron.
Neutrons are neutrally charged subatomic particles.
Yes.
Neutron
A proton is a subatomic particle which is the same in whichever element it is found. A proton from a Xenon atom is no different to that from a Hydrogen atom or a Uranium atom.
Neutrons
There are many subatomic particles with negative charge, but the first negatively charged particle that anyone learns about is the electron. It is only invisible in the sense that humans can not see it because it is so small. It is a perfectly normal subatomic particle and certainly the most common negatively charged particle in the universe.
A positively charged subatomic particle is a proton. Protons are found within the nucleus of an atom and carry a positive electrical charge.
