Question

sub atomic particles founded by in a atom

Answer 1

The sub atomic particles found in an atom are
1) Protons - A proton is a subatomic particle, symbol p or p+ , with a positive electric charge of +1e elementary charge and mass slightly less than that of a neutron. 

2) Electron - Is is a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.

3)Neutron - The neutron is a subatomic particle, symbol n or n0 , with no net electric charge and a mass slightly larger than that of a proton. Protons and neutrons constitute the nuclei of atoms.

Answer 2

Three subatomic particles are Proton with positive charge, Neutron have no charge, and Electron with negative charge
