Two elements that are liquid at room temperature are Mercury ( Hg) and Bromine( Br).
Mercury(Hg) is a shiny silvery metal that we see in thermometers. It is liquid at room temperature because the bonds between the atoms of mercury are much weaker as compared to the other metals.
Bromine(Br) is a reddish-brown liquid. The intermolecular force of attraction is strong in the particles of bromine so therefore they do not vaporize easily and are liquid at room temperature.
