Basics of Chemistry Part-04   (Valancy, charge & ions ) In the previous three parts of this series, we have learnt about details of first 20 elements, calculated their atomic weight, drawn their atomic structures and learnt about shell & sub-shell electronic configurations. Not seen Part-1, Part-2 & Part-3 yet?? Click here for Basics of Chemistry || Part-01 || Click here for Basics of Chemistry || Part-02 ||   Click here for Basics of Chemistry || Part-03 || In this part we will be discussing about valencies and radicals of the first 20 elements about which we have studied in previous parts. We will first learn to calculate valencies from shell and sub-shell electronic configurations and then we will be looking towards ions. So, let us start without any delay... After understanding shell electronic configuration, it is easy to predict valencies of the elements just by looking their last number. For example, the Electronic configuration (E.C.) of Lithium i...
