Narrative:

On approach at about 1;800 ft and visual the first officer noticed a trailing edge flap asymmetry between flaps 2 and 5 after I requested flaps 10. I executed a go around; advised ATC of the situation and requested radar vectors to accomplish the non-normal checklist for a trailing edge flap asymmetry. I declared an emergency; requested emergency equipment standing by and; after completing all required checklists and checking all required performance data; landed without any further events.
