also, if i have an ion for example Al^{3+} what is its lewis structure, this ion is like noble gas Ne as far as valent electrons, so is its lewis structure just [Al]^{3+} , no dots or lines?

I think you're right on the Al3+.

The other question, did you mean this picture below?

Well, I am not very sure but they look okie to me!
