What is the charge and mass of a neutron?

The neutron is a subatomic particle found in the nucleus of an atom. It carries no electric charge, which is why its charge is represented as 0. This neutral charge means that neutrons do not contribute to the electrical properties of an atom, differing from protons, which have a positive charge.

Regarding mass, a neutron has a relative mass of approximately 1 atomic mass unit (amu), which is a standard measurement used in chemistry to express the mass of atoms and subatomic particles. This mass is approximately equal to that of a proton, though neutrons are slightly heavier. The mass of 1 amu for a neutron is reflected in its presence in the atomic nucleus, where it contributes significantly to the overall mass of an atom when combined with protons.

Therefore, the statement that correctly identifies the charge as 0 and the mass as 1 accurately describes the fundamental characteristics of a neutron.
