I'm not sure how to work this out, what's the answer please 1s2 2s2 2p6 3s2 3p1
We can only guess what you are looking for Did you leave something out of your question? The only thing I can think of is if you are wondering about the ability of aluminum foil to reflect heatSome people put aluminum foil on windows to reflect heatThis would help reduce run time on air conditioners.
1s2 2s2 2p6 3s2 3p1 ?? Clearly, this is aluminum, which has one p-electron and three valence electrons[1s2 2s2 2p6] 3s2 3p1 where [.] indicates the ten inert gas core electrons We can condense the core electrons and represent them with the symbol of the inert gas[Ne] 3s2 3p1 and 3s2 3p1 represent the three valence electrons.
