All the following metal elements are liquids at or near room temperature except for beryllium. Beryllium is not a liquid at or near room temperature because it has a high melting point of 1287°C (2349°F). The other metal elements mentioned, including mercury, gallium, and cesium, have melting points below or close to room temperature, which allows them to exist in liquid form at normal atmospheric conditions. However, beryllium requires significantly higher temperatures to melt and transition into a liquid state.
