how many electrons are in the outer shell of aluminum?
You will burn more gas in your car taking just 500 mixed metal cases to a recycle placeThrow them awayNow, if you could gather up the molten lead it may bring a couple of dollarsSad story,but you will be better off to can the idea.
The composition of the cases would probably be confirmed by your recycling facility, IF they are willing to take spent ammunition Everybody else has touched on the wide variety of case materials, and if they are very orange it might be copper clad steel cases/russian ammo I have tried to recycle deprimed, unloaded cases before and they wont take it due to company policy of no munitions components.
A lot of foreign cases are steel and are worth $150/tonSome foreign steel cases have a very thin layer of plastic, copper, zinc, or lacquer on themThey would recycle as steelAll of the US cases that I know of are brass.
most ammo cases are brass but a few are steel or aluminum the 'tip' is really the bullet, the actual projectileMost of them are lead with a copper coatingbut if you just want to get rid of it then take it to the recycler.
look at the periodic tablewhatever group it is (in columns going down) is how many valence/outer electrons it has facstaff.gpc.edu/~pgore/PhysicalScience/periodic-table.gif aluminum is in group 3, therefore it has 3 valence electrons
