Atomic Structure

An atomic structure by a textbook definition is, an arrangement of the subatomic parts of an atom around a positively charged nucleus located at the center of the atom, surrounded by a cloud of negatively charged electrons in different orbits. The arrangement and the number of electrons alters according to different elements. The idea of an atom and its atomic structure is a key factor in the subject of physics and chemistry. Read on to explore the 'simply complex' structure of an atom!
