First of all, I have never even attempted to learn the periodic table out of my head, simply because it's not really useful to me. And silver I just know out of my head, because I've seen it so much. I haven't really related an image to it though... I do that mostly with harder-to-memorize things, like certain word combinations.

Right. It is indeed rather a fun project than the most useful skill in the world. But it is so easy that you can learn all 118 in an hour. And that is pretty impressive. :)
