What do electrons revolve around in an atom?

Electrons revolve around the nucleus of an atom. The nucleus is the central part of the atom and consists of protons and neutrons. It carries a positive charge due to the presence of protons, which helps to attract the negatively charged electrons. This attraction keeps the electrons in orbit around the nucleus, much like planets orbiting the sun. The arrangement and behavior of electrons are fundamental to the chemical properties of elements and how they interact with one another. Understanding this relationship between the nucleus and electrons is crucial for grasping concepts in chemistry and physics, such as atomic structure and bonding.
