Question

A neutron has a mass A. that is less than the mass of an electron. B. that is about equal to the mass of an electron. C. that is about equal to the mass of a proton. D. that is less than the mass of a proton.

Answer 1

A neutron has a mass that is about equal to the mass of a proton, approximately 1.0087 amu, while an electron has a much smaller mass of about 0.00055 amu.

Step-by-step explanation:

A neutron has a mass that is about equal to the mass of a proton. While the exact values can vary slightly due to isotopic differences, generally, a neutron is indeed slightly heavier than a proton, with a mass of approximately 1.0087 atomic mass units (amu), and a proton has a mass of approximately 1.0073 amu. In contrast, an electron is a much lighter particle with a mass of about 0.00055 amu. This significant difference in mass means that it would take about 1,836 electrons to equal the mass of one proton or neutron. The correct answer, therefore, is option C, that a neutron's mass is about equal to the mass of a proton.

Answer 2

Option C:- that is equal to mass of an proton.

Step-by-step explanation:

Protons and neutrons have approximately the same mass, about 1.67 × 10-24 grams, which scientists define as one atomic mass unit (amu) or one Dalton. While electron has mass of 9.31 ×10⁻¹⁹.
