Ionic Compounds

Postby Yeo Bin Yook 1K » Wed May 23, 2018 12:36 pm

I was working on homework 3.39 and they ask for the Lewis Structure of a compound. However in the solutions, it seems like from the given information I am supposed to know that the compounds are ionic compounds and therefore they use brackets and charges.

Is there a way to automatically know that such a compound is an ionic compound like ammonium chloride or potassium phosphide?

If you break up the individual molecules, you'll be able to recognize if it's ionic. In the case of ammonium chloride, NH4 has a positive charge (NH4+) while chlorine has a negative charge (Cl-). These opposite charges indicate that it's an ionic compound. Hope this helped!

Also, usually ionic compounds occur when nonmetals and metals exchange electrons while covalent bonds are the sharing of electrons between two nonmetals. This will allow you to look at the types of elements involved in the compound and figure out what type of bond is occurring between them.
