An atomic structure can be defined as the structure of the positive nucleus and the negatively charged electrons in an atom while the crystal structure is the specific arrangement of atoms and how they are interconnected making a whole uniform structure.
Read this one if unclear about the crystal structure. July 13, July 31, June 20, July 31, Your email address will not be published.

Arrangement: The arrangement in atomic structure and crystal structure do vary: In an atomic structure, the arrangement of particles is in subatomic form in atoms while for the crystal structure the arrangement is composed of atoms or molecules which are usually in crystal form.
Mass: Atomic structure is smaller in mass compared to crystal structure. A crystal structure has a bigger mass as compared to an atomic crystal because of the high composition of molecules in a crystal structure. Atomic Structure vs Crystal Structure. In this article, main focus is on the internal arrangement of an atom and a crystal. What we see from outside is a result of the internal arrangement of atoms or molecules.
Sometimes, the external view may be different from the internal structure; but they are not completely independent of each other. Atoms are the small building blocks of all existing substances. Normally, atoms are in the Angstrom range. With the discovery of subatomic particles, the next question for scientists was to find how they are arranged in an atom.
In , Thompson presented the plum pudding model to explain the atomic structure. This said that electrons are scattered in a sphere where there are also positive charges scattered to neutralize the negative charges.
Later Ernest Rutherford did an experiment that led to the finding of more accurate details about the atomic structure. They fired alpha particles to a thin gold foil and found out following data.
