Question
An element has an electric charge +1. It is for which sub-atomic particle ?
- Electron
- Proton
- Neutron
- Positron
Hint:
The protons are the subatomic particles that have a +1 electric charge.
The correct answer is: Proton
- In an atom, the protons are positively charged, neutrons have no electric charge and the electrons have a negative electric charge.
- Protons are found inside the nucleus as tiny particles with 1 atomic mass unit.
- Protons are subatomic particles that have a positive electric charge +1.
