The atomic structure is the structure of an atom, theoretically consisting of a positively charged nucleus surrounded and neutralized by negatively charged electrons revolving in orbits at varying distanced from the nucleus, the record of the nucleus and the arrangement of the electrons differing with various chemical members. Over meter, the atomic structure has been changed or even interpreted differently. For example, some bulk model that there was no positive or no negative in the atom, meanwhile some people thought that there was. several(prenominal) thought that there were fixed paths between the positive and negative charges (meaning the proton or electron), others thought that they were randomly fixed in the atom. Some models created over time were by famous people such as Dalton, Thomson, Rutherford, Bhors, and what we involve now which is the wave mechanical method.

John Dalton was an English chemist, meteorologist and physicist. He is best known for his pioneering work in the development of fresh atomic theory, and his research into color blindness. His atomic theory fundamentally explained that the atom cannot be divided. According to him, all elements are make of atoms and the purity of an element is attributed to the presence of similar atoms.
John Dalton believed that the atoms of an element cannot be created, destroyed, broken into smaller parts or alter into atoms of another element. Dalton based this hypothesis on the law of saving of mass and on centuries of experimental evidence. With the discovery of subatomic particles later on Daltons time, it became apparent that atoms could be broken into smaller parts. The discovery of thermonuclear processes showed that it was even possible to transform atoms from one element into atoms of another.Â
Some ideas that were proposed were:
All matter is composed of atoms
Atoms cannot be made or destroyed
All atoms of the same element are identical
