This is what I'm thinking. Xe, Rn and Kr are all noble gases. That are non reactive. Their outer shell of electrons are full. They have a complete octet, but Ag is not and we know silver clumps together and it can share its electrons. So I say Ag is the answer.

Ag (silver) is the answer, because the conditions stated are 1 atm pressure and room temperature (25 C). At that temperature and pressure all the other substances are gases, and the pictures shows a solid.

It was because of the temperature and the part about being a solid. Thanks!
