The electric charge that is associated with a\xa0neutron\xa0is 0. Therefore,\xa0neutrons\xa0are neutrally charged subatomic particles. The\xa0mass\xa0of a\xa0neutron\xa0is roughly equal to 1.008 atomic\xa0mass\xa0units. When converted into kilograms, the\xa0mass\xa0of the\xa0neutron\xa0can be approximated to 1.674*10-27 kg

Mass of a neutron is 1.008930 amu (1.6753\xa0x\xa010–24g or 1.6753\xa0x\xa010–27\xa0kg)Neutron “A sub-atomic particle, which is a fundamental constituent of matter having mass approximately equal to the hydrogen atom and which is electrically neutral, is called a neutron”.\xa0
