What is the structure of an atom?

The structure of an atom is characterized by a central nucleus that contains protons and neutrons. Protons carry a positive charge, while neutrons are neutral. Surrounding this nucleus are electrons, which carry a negative charge and occupy regions of space known as electron shells or orbitals. The arrangement of protons and neutrons in the nucleus contributes to the atomic mass, while the number of electrons determines the atom's chemical behavior and interactions with other atoms.

This model aligns with the widely accepted atomic theory in physics and chemistry, illustrating the organization and balance of positive and negative charges within the atom. It effectively explains fundamental concepts such as atomic stability and the formation of chemical bonds.
