Complete the lewis structure of the molecule. Draw the missing dots and dashes representing the valance electrons in the molecule. Thank you !

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
