PERIOD 3 OXIDESThis page explains the relationship between the carnal properties of the oxides of boundary 3 elements (sodium to chlorine) and their grammatical constructions. Argon is obviously omitted because it doesnt engineer 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 compass point 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 outmost electrons.| | Note:  If you arent sure about oxidation states (oxidation numbers) you get off discovery them discussed in if you follow this link.Use the BACK button on your web browser to return quickly to this page later.| The buildingsThe tr end 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 pick outed 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 - approximately 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 forever 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 expect to get a full essay, order it on our website: BestEssayCheap.com
