Which sub-atomic particle has the smallest mass compared to the others?
- Neutron
- Orbital
- Electron (correct)
- Proton
Why will a proton be deflected towards the negative plate in an electric field?
Why will a proton be deflected towards the negative plate in an electric field?
- Because it is negatively charged
- Because it is lighter than an electron
- Because it is positively charged (correct)
- Because it is neutral
What is the main reason electrons do not move in fixed orbits around the nucleus?
What is the main reason electrons do not move in fixed orbits around the nucleus?
- Due to the absence of orbitals
- Because of their small mass and wave-like nature (correct)
- Because of their neutral charge
- Due to their mass being too large
