Question 5 5. What subatomic particle has no electrical charge?
•neutron
•proton
•electron
•atom

Neutrons have no electrical charge

protons have a positive charge

electrons have a negative charge

Atoms mainly consist of a positively charged nucleus surrounded by one more negatively charged electrons, but overall the atom has no charge so it would neutral!

hope this helps!!
