When an Aluminum atom loses electron(s) (because it is closer to 0 then 8, what ion is formed.I've tried everything but OWL homework program wont accept any of my answers.any ideas?
Any insulation you get in those walls is better than nothingI would use rock wool or fiberglass blown in rather than an formaldehyde based foamI've heard bad things about toxic vapors with formaldehyde based products.
Blow-in insulation is installed by drilling holes in the interior wall plaster, usually two per stud bay as there may be fire blocking half way upThese holes will have to be patched and the wall re-painted or at least touched upI've found that upgrading windows yeilds a greater effect.
Cavity wall insulation is supported by government grantYou should call your local council and ask them about their local schemeThey will recommend their approved installers who will send round someone to survey your propertyThe actual cost could be several thousand pounds if you arrange a private jobBut the subsidised scheme could be as low as ?150-?200 for youIt depends on the surface area of your walls and whether you're detached or notExpect a wait of a month or two for the job to be done because subsised work is popularWhile you're about it ask about the loft insualtion scheme tooIt's well worth it thoughProviding that you don't leave doors and windows open you'll notice that your house holds the heat better so your boiler won't be on so much and you'll save money.

Aluminium is in group IIIA in the periodic table If you look to the left you will see that it is in the third periodIt donates 2 outer electrons and the single one it has in IIIA, In other words it donates its 3s2 and 3p1 electrons therefore leaving it with a positive charge of 3+.
