What is an atom and atomic structure?Atom, the smallest unit of substances or matter divided into charged particles (electron, proton, neutron). The smallest unit or basic building block of matter also contains the same characteristics properties of constituent elements in chemistry or physics. In the atomic structure, we deal with topics related to the structure, composition, and properties of atoms made from matter.
