Basics of Chemistry

Part-02 (Atomic structure of first 20 elements)

In the previous part we learnt about details of first 20 element and we calculated atomic weight of them. That was the first and most important step in studying chemistry. Without understanding about elements, their symbol and valancy, it is impossible to understand chemistry. So, for that, we have to first draw and understand the atomic structure of all first 20 elements.
