    Consider the physical states of CL2, K, W, Pb, Hg, Br2, and Sb. Which will be liquids at 25deg C?

    The answer is Hg adn Br2.

    How do you know Br2 is a liquid at RT?

    Just something you gotta know. With the halogens, chlorine is a gas at room temp, bromine a liquid, and iodine a solid due to increasing molar mass.
