Atomic models are important because, they help us visualize the interior of atoms and molecules, and thereby predicting properties of matter.

Explanation:

We study the various atomic models in our course of study because, it is important for us to know, how did people come to the present concept of an atom. How did physics evolve from classical to quantum physics.

All these are important for us to know and thus, knowledge about various atomic models, their discoveries and drawbacks and finally improvements based on scientific evidence present at that time is important for us to understand the underlying theory very well.

After World War 2 Soviet union immediately assumed control over Eastern Europe to create a buffer zone between Russia and Europe.

Explanation:

In 1945, the war ended and Soviets controlled much of Eastern European territory. they wanted to create a buffer zone between them and other powers. By 1948 the taking over was complete.
