Lewis Dot Structure Example

Postby Caroline C 1G » Wed Oct 25, 2017 10:14 pm

In lecture we drew the Lewis Dot structure for Ammonium Sulfate by drawing two diagrams, one for NH4, and the other for SO4. Is it possible to draw one diagram for Ammonium Sulfate as a whole? In other words, are NH4 and SO4 bonded in anyway?

NH4+ and SO4- are held together by ionic bonds. The Lewis dot diagrams represent covalent bonding so you can't use it to represent the entire ionic compound.

Actually he drew the Lewis dot structures for salts like KF. The only difference was that he used square brackets to differentiate the individual charges of the ions. So, I believe you could do the same for ammonium sulfate (there would be two ammonium ions since it has a plus one charge while sulfate has a minus 2 charge) if you isolate the three ions with square brackets and their charges.

Two (NH4)+ and one (SO4)2- can bond together by ionic bond and form (NH4)2SO4. When you draw the Lewis Dot structure, make sure to put the (NH4)+ on the left and (SO4)2- on the right.
