Narrative:

We had flown four legs in aircraft X. On the fifth leg; I was the pilot monitoring (pm). On the approach to runway xxr; I noticed we did not have any trailing edge flap or led indication with the gear extended and the flap handle selected to the 25 position. I took control of the aircraft at this point and now became the pilot flying (PF). I immediately told the tower we were going around (1500 ft AGL); accelerated to 210 KTS; and climbed to 3000 ft to engage the a autopilot. First thing we checked were the circuit breakers and we both confirmed no breakers were out. Wanting to try one more time to obtain flaps with the flap handle; I called for flaps to the 5 position. Nothing; no trailing flaps or leading edge devices would come out. We then ran the symmetrical non-normal trailing edge flap or no flap checklist. To my surprise; the trailing edge flaps still did not extend; however; we were able to get the leading edge devices extended. At this point I sent the first officer to the cabin to confirm our no trailing edge flap situation. He returned and it was what it was! We returned the flap handle back to up and proceeded with the checklist and declared an emergency. I briefed the flight attendants and the passengers to our situation and got back to work. Luckily; we were light on passengers and fuel. We had the performance to land and landed without incident utilizing max auto brakes. V target was 164 KTS. All hydraulic systems were operating with proper fluid levels. We never had any other master caution light illuminated. I did confirm after landing that the stby pump was operating as I was in the wheel well performing a post-flight walkaround. All crewmembers performed to company standards.
