Question

Neutrons are made up of one up quark and two down quarks and the quarks have chare.....

So why neutrons do not have charge ?

Solution

A neutron, like the name implies, is neutral with no net charge.
The charge is believed to be from the charge of the quarks that make up the nucleons (protons and neutrons). A proton is made of two Up quarks, with 2/3 positive charge each and one Down Quark with a negative 1/3 charge (2/3 + 2/3 + -1/3 = 1). A neutron is made up of two Down quarks with a negative 1/3 charge each and one Up quark with a positive 2/3 charge. (-1/3 + -1/3 + 2/3 = 0).
