PERIOD 3 OXIDESThis page explains the relationship between the physical properties of the oxides of boundary 3 elements (sodium to chlorine) and their grammatical constructions. Argon is obviously omitted because it doesnt sorting 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 item 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 outer(prenominal) electrons.| | Note:  If you arent sure about oxidation states (oxidation numbers) you bury find them discussed in if you follow this link.Use the BACK button on your web browser to return quickly to this page later.| The social organisations 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 take oned 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 - some(prenominal) small and simple; others polymeric.The attractive forces between these molecules allow be van der Waals dispersion and dipole-dipole interactions. These vary in size depending on the size, shape and polarity of the various molecules - but will continuously 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 compliments to get a full essay, order it on our website: BestEssayCheap.com
