He electron-dot notation
WebA Lewis electron dot diagram (or electron dot diagram or a Lewis diagram or a Lewis structure) is a representation of the valence electrons of an atom that uses dots around the symbol of the element. The number of dots equals the number of valence electrons in the atom. These dots are arranged to the right and left and above and below the ... Webelectron dot notation and the electronegativities of the elements. In order to do so the students must draw the electron dot notation for each element. They must also look up the Electronegativity of each element and find the mathematical difference between them. This difference is compared to a standard in order to determine the type of ...
