Basics of Chemistry Part-03   (Shell and Sub-shell Electronic configuration ) In the previous two parts of this series, we have learnt about details of first 20 elements, calculated their atomic weight and drawn their atomic structures.  Not seen Part-1 and Part-2 yet?? Click here for Basics of Chemistry || Part-01 || Click here for Basics of Chemistry || Part-02 || In this part we will be discussing about shell(orbit) and sub-shell(orbital) electronic configuration of first 20 elements. We will learn how to write these electronic configurations and what information can be obtained from them. So, let us start... As we have seen in the atomic structure, the first shell (orbit) can accommodate maximum 2 electrons, we will first try to put 2 electrons in 1st orbit i.e., K-Shell (orbit). But, Hydrogen contains only 1 electron as a whole, so it contains only 1 electron in the 1st shell (Orbit). Then, the 2nd orbit i.e., L-Shell can accommodate maximum 8 electrons. So, we will ...
