Atomic Structure

As you know!!

Atom means indivisible

Atom was considered as the smallest indivisible particle of the matter.

According to Dalton’s Atomic Theory, an atom is smallest indivisible particle of the matter. But later researcher have proved that atom is no longer consider as indivisible. It has been divided into so many other particles(more than 100 sub-atomic particles).

Fundamental particles are electrons, protons and neutrons. This idea has been taken from the results of several experiments. The most important are discuss in below notes:
