Question:

Write the electron configuration for an aluminum cation with a charge of +2?

i know the aluminum's electron configuration is 1s^2 s^2 p^6 3s^2 p^1 how would i write it with a +2.

Answer:

No actually it makes it worse, aluminum amplifies radio signals.(like an antenna)
I play a Britney Spears song to them.
Watch 'Signs' this movie is the best example of alien defense I have yet to find, keep water in random glasses around your houseAny aliens that attack this planet, which happens to be covered by water, are always going to be deathly allergic to waterOh, and having asthma will help you in the long runAll the answers are in hollywood, you just have to lookThe foil does nothing but add cometic relief.
1s^2 2s^2 2p^6 3s^1 or in short-hand notation: [Ne] 3s^1 However, aluminum is a +3 cation and not +2 cation.
