I don't get how to do chemical bondingFor example:Aluminum (3 valence elctrons) and chlorine (7 valence electrons)What's the formula for this?Please tell me how to do it in steps
Corrosion resistance, thermal conductivity, light weight, easily cleaned.
1Aluminium doesn't corrode easily,if it corrodes, it reacts with oxygen to form a layer of aluminium oxide around it, which protects it from further corrosion2It's lighter 3It can withstand high temperature.
it conducts heat quickly because it is a metalhence, heat is able to pass through aluminium into the food in the cooking pot for examplefurther more, it is durable and doesn't break easilyit is also a very light metal, hence, people can hold aluminium stuff easily, compared to copperthis is also the reason why electrical cables are usually made of aluminium instead of copperbecause cables are hung on top of poles and the cables need to be light so that they don't sag down.
You can think of this (more or less) as an ionic bonding problemAluminum is a metal and will lose its valence electrons to make Al3+ Chlorine with 7 electrons will gain 1 electron to attain the 8-electron noble gas configurationSo each chlorine will gain just one electron to make Cl- Electrons are neither created or destroyed, and aluminum chloride is neutralDoes that help?
This is bcoz its surface is coated with oxide layer which prevent further oxidation This oxide layer does not removes on heating .
