- 2What are the three subtonic particles ?protons , neutrons and electrons
- 3Where do the subtonic particles stay ?Nucleus apart from electrons they orbit the nucleus
- 4what determines the number of protonsThe element in the atom
- 5Proton relative charge / mass -relative charge - + 1
relative mass - 1 - 6neutron relative charge / mass -relative charge - 0
relative mass - 1 - 7electron relative charge / mass -Relative charge = - 1
relative mass - tiny , 2000 electrons to have the same mass as one proton or neutron - 8—
