what is the mass of a neutron?\no 1/2,000 amu\no 1 amu\no 2,000 amu\no 1/200 amu
Answer
Brief Explanations:
The mass of a neutron is approximately 1 atomic - mass unit (amu). This is a well - known fact in atomic structure studies in the field of Physics. Protons and neutrons have similar masses, while electrons have a much smaller mass (about 1/2000 amu).
Answer:
1 amu
