Question

graded formative: unit 2 study guide part 1 how do the masses of protons, neutrons, and electrons compare? mass of proton: 1 mass of neutron: 1 mass of electron

Explanation:

Step1: Recall particle - mass facts

Protons and neutrons have approximately the same mass. In atomic mass units (amu), the mass of a proton is about 1 amu and the mass of a neutron is about 1 amu.

Step2: Recall electron - mass fact

The mass of an electron is much smaller than that of a proton or neutron. In relative terms, the mass of an electron is approximately 0 amu when compared to protons and neutrons on the scale where protons and neutrons have a mass of about 1 amu.

Answer:

0
