An electron dot diagram is a method of writing the chemical symbol of an element by surrounding it with dots to indicate the number of valence electrons. Valence electrons are found in an atom's outer shell and are the ones involved in chemical reactions.
The Lewis dot structure of a nitrogen atom would be the capitol letter N with the five valence electrons represented by two dots above it, one to the left right and bottom of â¦ it.  .. . N.  .f you are looking at a nitrogen atom by itself it will have 5 electrons (dots) surrounding it. The number of dots corresponds to an atom's location on the periodic table. St â¦ arting from left to right (excluding transition metals) you increase 1 electron per column.
