Which subatomic particle orbits around the nucleus of an atom?

Neutrons
Protons
Electrons
Nuclei

The correct answer is: Electrons

Electrons are the subatomic particles that orbit around the nucleus of an atom. They are negatively charged and are found in designated energy levels or shells surrounding the nucleus, which contains protons and neutrons. The movement of electrons in these energy shells is crucial for understanding how atoms interact and bond with one another, which is fundamental to the study of chemistry and by extension, esthetics. Neutrons and protons, on the other hand, are located within the nucleus of the atom. Neutrons are neutral particles, while protons are positively charged. The option related to nuclei refers to the central part of the atom, rather than a subatomic particle that orbits. Understanding the role of electrons and their behavior is essential for estheticians, especially when discussing skin chemistry and the effects of various treatments.
