If this is for a fence slat use a # 8 galvinized, if it's for a 2x4 railing use a 16 D galvinized. If you want a better hold use a star head deck screw these are easier to screw in than a phillps head and can be removed easier too.
A galvanized nail will have a shiny, metallic coating on its surface, while a non-galvanized nail will have a dull, matte finish. You can also use a magnet - a galvanized nail will not be attracted to a magnet, while a non-galvanized nail will.
