Predict whether each of the following compounds is molecular or ionic: (c) Sc2O3
Alright guys, so remember, your molecular compound is when you have non-metals covalently bonded, and your ionic compound is when you have a cation plus an anion, or you could have a metal and a non-metal together.
So here we have Se2O3. Sorry this is supposed to be c not e (*Sc2O3). So, let's break this down. So we have Sc and we have O. Now, O is going to be a non-metal. Sc is actually going to be one of your metals. All you have to do is look at the periodic table and see where they're placed. Since we have a metal with a non-metal, we're going to assume this is going to be an ionic compound.
Alright guys, let's move on.
