Gold has the highest what for the ability to be pulled into then water?
You will have to re-ask this question.........
I do realize that some students do not have English as their first language, yet as it stands I don't know for what you are looking here. Gold is a soft, dense metal; and given that gold is also beautiful and does not tarnish readily, gold films and gold leaf have been historically used for artwork and lettering.
Anyway, please have another go, and someone will help you.
