Atomic structure is the structure of an atom that consists of a nucleus (the centre) and protons (positively charged) and neutrons (neutral). The electrons, which are negatively charged particles, circle around the nucleus’s centre.
Background:
Atomic structure:
The composition of an element’s nucleus and the arrangement of electrons around it are referred to as its atomic structure. Protons, electrons, and neutrons are the building blocks of matter’s atomic structure.

The Atomic Theory of Dalton:
All matter, according to English chemist John Dalton, is made up of indivisible and indestructible atoms. He also claimed that all atoms of a given element were the same, but that the size and mass of atoms of different elements differed.
According to Dalton’s atomic theory, chemical reactions require the rearrangement of atoms to generate products. The atomic structure, according to Dalton’s postulates, was made up of atoms, the smallest particles responsible for chemical reactions.
The following are his theory’s postulates:
The Laws of chemical reactions, such as the Law of conservation of mass, the Law of constant properties, the Law of multiple proportions, and the Law of reciprocal proportions, were successfully described by Dalton’s atomic theory.
