 Okay, let's try the second part of this problem Describe the following molecules as diatomic triatomic and or polyatomic so in chemistry and most things diet die means two and Atomic means that so diatomic means molecule composed of to at triatomic Tri means three and polyatomic means poly means many so polyatomic means in chemistry terms Anything that's got two or more so let's try to designate these as diatomic triatomic and or polyatomic Hopefully you can tell that anything that's diatomic or triatomic would also be polyatomic. You can keep going up Usually after triatomic, you don't say tetra and then stuff like that. You just do All right, so Homoatomic, I mean sorry O2 It's two atoms right two oxygens, so it actually looks like this two oxygens bond together, so we say Atomic and of course these are all going to be polyatomic So two oxygens one carbon and carbon dioxide triatomic and again two or more so it's poly and then carbon monoxide Diatomic Oxide very interesting like we said before actually we don't know anything about this That's a permanent dipole there, so Binds really well the hemoglobin because of that negative charge that's why carbon monoxide kills you actually But anyways, that's all beside the point the most important thing for you guys right now is this Diatomic triatomic polyatomic thing and we'll try one more Of these with our other example
