Question

by taking this checkpoint, you will check your understanding of the concepts youve been working on in this lesson. you may take the checkpoint multiple times. only your highest score will be recorded in the gradebook. if you scored poorly this time, go back and review the lesson activities you struggled with before taking the checkpoint again. ask your teacher for assistance if you need extra help. good luck! note: to answer some of the questions, it may help to reference a periodic table. what is the subatomic particle that has no charge, but has mass?
○ neutron
○ electron
○ proton
○ ion

Explanation:

To determine the subatomic particle with no charge but mass, we analyze each option:

• Neutron: Has no electric charge and a mass (similar to proton, slightly more than proton in some contexts, but significant mass).
• Electron: Has a negative charge and very little mass (much less than proton/neutron).
• Proton: Has a positive charge and mass.
• Ion: Not a subatomic particle but a charged atom/molecule.

So the neutron fits the description.

Answer:

A. neutron
