Atomic structure

Atomic structure in chemistry

Dalton's atomic theory regarded as the primary basis of the atomic structure and reactions in chemistry in the last century. All the chemical reactions in chemistry clearly explained by this theory.

But this concept based on the indivisibility and an atom is the smallest building block of an atom. Thus this structure discarded by the discovery of the several fundamental particles of the atom.

The modern atomic model

In our present-day electrons holds the key to chemical reactions and the structure of an atom. Thus the modern structure based on the electronic arrangement of the atom.

Today electrons considered as standing waves. Thus the probability of finding an electron in a particular region is called orbitals.

In this category, we can discuss step by step different atomic theory.
