alf63- sounds like a space creature and has no meaning in chemistry. Do you mean AlF63-?
This is an unusual structure. Since there's only one Al, that goes in the middle. Each of the Fluorines needs only one more electron (which each does through forming a single covalent bond), so draw each of the fluorines around the Al and draw a single line between the Al and each F to indicate a single bond.
Now that the skeleton's in place, make sure the electrons add up correctly. We'll add up all the valence electrons available to use (from Al and the 6 F, AND the 3 that make the -3 charge), and then we'll subtract what electrons we used to make the skeleton. here goes:
Al has 3 valence e-, and each F has 7 valence e-. 3 + 7×6 = 45. then we add the 3 e- for the -3 charge: 45+3 = 48 total e- to use in our structure. Now we count what we used up. Each F has 3 lone pairs of e- around it (wants a full octet, makes only one bond, this leaves 6 e- unbonded), so that accounts for 6×(2×3) electrons -- that's 6 Fluorines, and 2 electrons in each of 3 lone pairs around each flourine. this is 36 electrons used up from our 48 total. So we have 12 more to account for. For each flourine, you drew a single bond between the Flourine and the Al. a single bond is made of 2 electrons, so in total this is 6×2 electrons -- 6 Al-F bonds, and 2 electrons per bond. This is 12 electrons, so we've accounted for all 48 available electrons for our structure.
The correct structure has Al in the center with 6 Flourines single-bonded to it, and the whole structure carries a -3 charge.
No, not exactly. It is an ionic compound so it would not have a Lewis dot structure. However, the carbonate anion, CO3^2- does have a Lewis dot structure.

The nuclues.
The Lewis dot structure is a diagram to show the bonding between the atoms of a molecule and pairs of electrons that may exist. The Lewis dot structure for chromium is Cr with two dots on top and bottom, and four dots on both sides.
Will this link help you?, it is quite impossible to draw a Lewis dot structure in this simple text editor. See related links.
