Neutrons are neutral because they are composed of fundamental particles called quarks.

Here's the breakdown:

* Quarks: There are six types of quarks, and each has a specific electric charge.

* Up quark (u): +2/3 charge

* Down quark (d): -1/3 charge

* Neutron Composition: A neutron is made up of one up quark (u) and two down quarks (d).

* Calculating the Charge:

* The total charge of a neutron is the sum of the charges of its quarks: (+2/3) + (-1/3) + (-1/3) = 0.

Therefore, a neutron has a net charge of zero, making it electrically neutral.
