Drawing the Lewis Structure for AsO33- (Arsenic Trichloride)

Viewing Notes:

  • For the Lewis structure for AsO33- you'll need to add three additional valence electrons because of the 3- charge on the ion.
  • For the AsO33- Lewis structure there are a total of 26 valence electrons available.
  • The Arsenic atom goes in the center of the Lewis structure since it is the least electronegative atom.
  • Be sure to put brackets and a 3- around the AsO33- Lewis structure to show that it is an ion.
