PERIOD 3 OXIDESThis page explains the relationship between the   fleshly properties of the oxides of  boundary 3 elements (sodium to chlorine) and their  grammatical constructions. Argon is obviously omitted because it doesnt  arrive at an oxide.A quick summary of the trendsThe oxidesThe oxides well be looking at  be: Na2O| MgO| Al2O3| SiO2| P4O10| SO3| Cl2O7|   | | | | P4O6| SO2| Cl2O|  Those oxides in the top row are known as the highest oxides of the various elements. These are the oxides where the  menses 3 elements are in their highest oxidation states. In these oxides, all the  outside electrons in the Period 3 element are being involved in the bonding - from just the one with sodium, to all seven of chlorines  outermost electrons.|   | Note:  If you arent sure about oxidation states (oxidation numbers) you   decease   stripping them discussed in if you follow this link.Use the BACK button on your  web browser to return quickly to this page later.|   The  mental synthesiss   The trend in structure is from the metallic oxides containing giant structures of ions on the left of the period via a giant covalent oxide (silicon dioxide) in the middle to molecular oxides on the right.

Melting and boiling pointsThe giant structures (the metal oxides and silicon dioxide)  leave behind have high melting and boiling points because a  hoi polloi of energy is  learned to break the strong bonds (ionic or covalent)  in operation(p) in three dimensions.The oxides of phosphorus, sulphur and chlorine consist of  individual(a) molecules -  just about small and simple; others polymeric.The attractive forces be   tween these molecules  allow be van der Waal!   s dispersion and dipole-dipole interactions. These vary in  size depending on the size, shape and polarity of the various molecules - but will  everlastingly be much weaker than the ionic or covalent bonds you need to break in a giant structure.These oxides  hightail it to be gases, liquids or low melting point solids. galvanising conductivityNone of these oxides has...If you  involve to get a full essay, order it on our website:
