What are Atomic Models?

Atomic models are theories of how atoms are structured. These theories aim to describe the structure of atoms and explain their behaviour and characteristics. 

The models of atomic structure have developed over time as new discoveries of particles have given us more and more information. We currently use the Bohr Model to explain how atoms are structured, this is an extension of the Rutherford Model that also explains why negatively charged electrons do not fall into the positively charged nucleus of atoms. This is because the electrons are arranged in specific energy levels and need to gain or lose energy to move to different levels. 

JJ. Thomson (pictured right) proposed the Plum Pudding model after his groundbreaking discovery of negatively charged particles inside atoms.
