Human Factors
The weather was clear; and my First Officer and I were having a conversation as we passed through 10;000 ft MSL. I turned on the sterile cockpit light; but did not cease the conversation as I should have.We had been cleared for the approach; and everything was set up for the RNAV P 24R; when I noticed that I was rapidly approaching the final approach fix; and I hadn't begun configuring the aircraft for landing. We were slow enough to call for flaps 1; flaps 5 and gear down; but as we began to descend on the glide path (and I was able to call for flaps 15) we had trouble slowing below 180 kias.I believe we were between 600 and 800 ft when I initiated the go-around. I pushed TOGA (Take-Off / Go-Around); and made the initial call outs through flaps 15; but then focused on what the tower was telling us to do instead of continuing to focus on the configuration of the aircraft.The flaps 15 placard speed was exceeded. The FO (First Officer) called it out; and the flaps were retracted; but not in time to avoid an overspeed of flaps 1 as they were retracting to flaps up.We were vectored to the northeast for another approach; which; along with the landing was completed uneventfully.Upon completion of the parking checklist; we thoroughly debriefed the event; and concluded that we needed to inform maintenance of the overspeed. At that point; a mechanic met the airplane; and I told him what happened. He acknowledged and thanked me for the information.
Air Carrier Captain reported an unstable approach; missed approach; and flap overspeed.
