Question

what is the mass of a neutron?
1/2,000 amu
1 amu
2,000 amu
1/200 amu

Explanation:

In atomic physics (a subfield of Natural Science, specifically Physics), the mass of a neutron is approximately 1 atomic mass unit (amu). The mass of an electron is about 1/2000 amu, while protons and neutrons have masses close to 1 amu. So we identify the correct option based on this knowledge.

Answer:

B. 1 amu (assuming the options are labeled as A. 1/2,000 amu, B. 1 amu, C. 2,000 amu, D. 1/200 amu)
