Question

students are completing a table about a particular subatomic particle that helps make up an atom.

mass (amu)	location	charge

what best explains how they should complete the table?

• with \inside the nucleus,\ because the particle is a proton
• with \inside the nucleus,\ because the particle is a neutron
• with \outside of the nucleus,\ because the particle is a proton
• with \outside of the nucleus,\ because the particle is an electron

Explanation:

Protons and neutrons are in the nucleus. Protons have a mass of about 1 amu and neutrons have a mass of about 1 amu. Electrons have a mass of approximately $\frac{1}{2000}$ amu and are outside the nucleus. Since the particle has a small mass and a charge, it is an electron.

Answer:

with “Outside of the nucleus,” because the particle is an electron
