Which Lewis electron-dot diagram correctly represents the reactant containing nitrogen in the equation?
Option (1) represents the Lewis electron-dot diagram correctly containing nitrogen in the equation.
Lewis Structure is a very simplified representation of the valence shell electrons in a molecule. It is used to show how the electrons are arranged around individual atoms in a molecule. Electrons are shown as "dots" or for bonding electrons as a line between the two atoms.
Valence electrons are given by hydrogen atoms = [tex]1\times3=3[/tex]
Valence electrons are given by nitrogen atom = [tex]5\times1=5[/tex]
Total valence electrons = 3 + 5 = 8
So, the calculation above is shown only the first option. So, (1) Lewis electron-dot diagram correctly represents the reactant containing nitrogen in the equation.
