 Okay, so let's do this one. Let's write the formula of these molecular or covalent compounds when we're given the name Okay, so I'm pretty straightforward. It actually tells you what it's supposed to be just remember when there's nothing in front of The first one. It's just one of them. So nitrogen monoxide is just nnO So notice we didn't put mono nitrogen monoxide. We just put nitrogen monoxide Why because the first one if there's only one you just put the name of them here dye nitrogen It's gonna be M2 tetroxide O4 tetra is for dye phosphorus, so P2 pentoxide O Nitrogen just one of them We'll build these structures eventually later in and we'll link this video back to that one Some of them are very interesting structures
