Discuss why aluminum forms a 3+ ion yet oxygen forms a 2+ ion? Include electron configurations?
Yes but it's not very sturdy.
yea i use alimium foil for everything
DefinitelyOr, just rub some butter on the tray and you should be fineOr do both.
they may burn on the bottom as the foil is far thinner than a sheet pan watch them closely
1s2 2s2 2p4 is O like other answerer indicated it is USUALLY considered a -2 ion because adding 2 electrons gets us to a full shell 2s2 2p6 HOWEVER, one exception is OF2 in which case O would be +2; but -2 is the norm - so assuming typo 2s2 2p6 3s2 3p1 is Al by losing 3 electrons 3s2 and 2p1 it beomes isoelectreonic with Ne a stable configuration
