Question

Which of the following is the main cause of late discovery of neutron?

• A. Neutron is highly unstable particle
• B. Neutron in nucleus moves very fast
• C. Neutron is charge-less particle
• D. All of the above

Answer 1

The correct option is C Neutron is charge-less particle

Initially, it was believed that the atom consisted of a small massive nucleus with a positive charge surrounded by a much larger cloud of negatively charged electrons.

Being charge-less particle, neutron did not show their influence in experiments performed for the discovery of charged particles electrons and protons.
