Let's look at your choices...

A. Neutrons travel around the nucleus of an atom. --> Hm...last time I heard ELECTRONS travel around the nucleus of an atom, so this is a false statement. :)

B. A neutron has no charge. --> This is CORRECT. But let's look at the other choices just in case. ;)

C. Neutrons have less mass than electrons. --> Another false statement. A neutron has approximately 1500 times the mass of an electron.

D. The number of neutrons in an atom always equals the number of electrons. --> This is usually not true. An atom will have an equal number of electrons and protons, but NOT neutrons.
