Basics of Chemistry Part-02   ( Atomic structure of f irst 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. Click here for  Basics of Chemistry || Part-01 || So, let us start... Atomic Structure of first 20 elements Atomic Structure of Hydrogen (H) Atomic Structure of Helium (He) Atomic Structure of Lithium (Li) Atomic Structure of Beryllium (Be) Atomic Structure of Boron (B) Atomic Structure of Carbon (C) Atomic Structure of Nitrogen (N) Atomic Structure of Oxygen (O) Atomic Structure of Fluorine (F) Atomic Structure of Neon (Ne) Atomic Structure of Sodium (Na) Atomic Structure of Magnesium (Mg) Atomic Structure of Aluminum (Al) Atomic Structure of Si
