Atomic Structure :
Atomic structure refers to the arrangement of subatomic
particles within an atom, which is the fundamental unit of matter. The
discovery of atomic structure evolved over time, with the central nucleus being
identified as a composition of positively charged protons and neutral neutrons.
Negatively charged electrons were later found to orbit the nucleus in energy
levels. The interaction between these particles determines the chemical and
physical properties of elements and compounds.
