Electron, lightest stable subatomic particle known. It carries a negative charge, which is considered the basic unit of electric charge. The rest mass of the electron is 9.109 × 10−31 kg, which is only 1/1,840the mass of a proton. An electron is therefore considered nearly massless in comparison with a proton or a neutron, and the electron mass is not included in calculating the mass number of an atom.

subatomic particle
What subatomic particle has a charge of -1?
This particle is the electron.
Is an electron a sub atomic particle in the nucleus that is attracted to electrons?
no. ions are made of relatively whole atoms (plus or minus a few electrons)
Which subatomic particle has no charge?
neutron
What subatomic particle always has a positive charge?
Protons are the subatomic particles which have positive charges.
What is the light est subatomic particle?
The lightest subatomic particle is the electron.
What subatomic particle has the less mass?
In the atom the electron is the lightest.
What subatomic particles are the lightweights of the atom?
The lightest particle in the atom is the electron.
What subatomic particle Has the smallest relative mass?
In the atom the electron is the lightest.
What is a subatomic particles with almost no mass?
The electron is the lightest particle in the atom.
Are the protons positively charged and the lightest subatomic particle?
Protons are positively charged but are not the lightest. They are about 2000 times the weight of electrons.
What is the lightest subatomic particle of an atom?
electrons the smallest but weigh as much as protons neutrons weigh nothing ~Kay
What subatomic particle has the lowest masses?
If you mean subatomic particle as in protons neutrons and electrons, electrons have the lowest mass. If you are talking even smaller, leptons have extremely tiny rest masses.
Is a colloid a subatomic particle?
A colloid is not a subatomic particle.
What is the subatomic particle with a neutral or no change?
The subatomic particle that has no charge is a neutron.
What is a negativily subatomic particle?
A negatively charged subatomic particle is an electron, or the antiproton.
Which subatomic particle has a negative chrage?
The electron is the subatomic particle with a negative charge.
