What component of an atom resolves around the nucleus and carries a negative charge?

An electron is a subatomic particle that orbits the nucleus of an atom and carries a negative electrical charge. Electrons are essential to the structure of atoms, as they help to determine an atom's chemical properties and how it interacts with other atoms. They exist in various energy levels or shells around the nucleus, which contains protons and neutrons.

The interaction between electrons and the positively charged protons in the nucleus is fundamental to the formation of chemical bonds and the overall stability of the atom. The arrangement and movement of electrons in these energy levels also play a role in electrical conductivity and the behavior of atoms in different states of matter. This understanding is crucial for students in the field of esthetics, as it provides the basis for understanding how substances might react during facial treatments, chemical peels, and other services that depend on molecular interactions.
