Step-by-step explanation:

Answer 2

The correct order of parts of an atom from most massive to least massive is nucleus, proton, electron.

Step-by-step explanation:

The correct group that lists the parts of an atom from the most massive to the least massive is D. nucleus, proton, electron.

1. The nucleus is the central part of an atom and contains protons and neutrons.
2. Protons are positively charged particles found in the nucleus and have a mass greater than electrons.
3. Electrons are negatively charged particles that orbit the nucleus and have the least amount of mass among the three subatomic particles.
