This question is about atoms. Atoms contain three types of particle: electrons, neutrons, and protons. Which particle has no electrical charge?
Answer options:
A.
Electron
B.
Neutron
C.
Proton
How to approach this question
Recall the properties of the three subatomic particles: protons, neutrons, and electrons. Identify which one has a neutral (zero) charge.
Full Answer
B.Neutron✓ Correct
Neutron
The three subatomic particles have different electrical charges. Protons are positive (+1), electrons are negative (-1), and neutrons are neutral (0). Therefore, the neutron is the particle with no electrical charge.
Common mistakes
✗ Confusing neutrons with electrons or protons.\n✗ Thinking electrons are neutral.
