This particle is the electron.
Protons
Probable you think to ions but ions are not subatomic particles.
no. ions are made of relatively whole atoms (plus or minus a few electrons)
A colloid is not a subatomic particle.
The lightest subatomic particle is the electron.
The subatomic particle that has no charge is a neutron.
they are called ions... an unbalanced atom with an additional subatomic particle is called ion...
A negatively charged subatomic particle is an electron, or the antiproton.
The electron is the subatomic particle with a negative charge.
particle whose dimensions is less then that of atom are said to be subatomic particle . they may be charged or uncharged .eg neutron is uncharged subatomic particle where as electron ,proton , positron are charged subatomic particle.
Not sure if you mean this... A neutral atom becomes an ion by losing or gaining electrons.
Protons and neutrons; these particles consist of quarks and gluons.
