what are the two parts of an atom? the nucleus and the proton cloud the neutron and the electron cloud the neutron and the proton cloud the nucleus and the electron cloud
Answer
Answer:
D. the nucleus and the electron cloud
Explanation:
Step1: Recall atom structure
An atom has a central nucleus.
Step2: Identify electron - related part
Surrounding the nucleus is the electron cloud. Protons and neutrons are in the nucleus, not in a separate 'proton cloud' or 'neutron cloud' as options suggest. So the two main parts of an atom are the nucleus and the electron cloud.
