 Okay guys, let's try to name covalent compounds now So when naming covalent compounds, of course, you got to recognize covalent compounds are between two non-metals And you use the prefix method. So if you Remember the prefixes are mono die tri tetra penta, etc So when naming compounds For the first atom if there's only one of them you don't use the mono, but that's it. Okay, so for this first compound We call it Carbon monoxide Notice we didn't say monocarbon monoxide So we use the mono only for the second atom This one since there's four phosphorus will say tetra Since that means four and phosphorus so the tetra phosphorus Five oxygens. Well, that's pent penta But for this one, I'll just be pent oxides SO3 remember if there's only one you just write the Name of the element if it comes first so sulfur tri oxy Because tri is the prefix for three This one of course has two nitrogens. So it's going to be die nitrogen I've oxygens And doxide and last We're going to have one carbon. So it's going to be just carbon and two sulfurs die Sulfide so good job guys It should be able to do these on your own
