+1. If you see, the first ionisation energy is very low, so it's rather easy to take an electron out of it. Na+2 or up are virtually non existent in nature (earthly nature, at least)

Indeed carlospvo... is correct. The charge of the Na ion is pretty much always +1. Not much of a chance in nature to go and loose an electron in the next lowest energy level.
Get an "A".

It would be -1because it is in the first group and gives away electrons
