Yes carbon disulfide is a liquid at room temperature. Carbon dioxide is however, a gas. CS2 is a liquid because of the higher molecular weight.

CS2 is a liquid at room temperature due to its molecular structure and intermolecular forces. The linear structure of the CS2 molecule allows for strong van der Waals forces between molecules, keeping them close together and in a liquid state at room temperature. Additionally, the presence of polar covalent bonds in the CS2 molecule contributes to its liquid state.
CS2 has stronger intermolecular forces, which result in a higher boiling point compared to CO2. CS2 molecules are more polarizable due to the presence of sulfur, leading to stronger London dispersion forces. As a result, CS2 exists as a liquid at room temperature while CO2, being nonpolar, exists as a gas.
CO2 is a gas at room temperature and pressure due to its low boiling point (-78.5°C) and Cs2 is a liquid because it has a higher boiling point (319.4°C). The different intermolecular forces between the molecules contribute to their physical states at room temperature.
Mercury is the only metal that is a liquid at room temperature.
Bromine is a liquid at room temperature.
Mercury is a metal that is a liquid at room temperature. It has a low melting point of -38.83°C, making it the only metal that is liquid at standard conditions for temperature and pressure.
