Explanation

Mercury is the only elemental metal that remains in a liquid state at room temperature (around 25°C).

It is used in thermometers, barometers, and other scientific instruments due to this unique property.

Four other elements are liquids slightly warmer than room temperature.

They are:

1. Francium
2. Cesium
3. Gallium
4. Rubidium

Explanation

Metals make up the majority of elements in the periodic table, especially on the left and center.

They are generally good conductors, malleable, ductile, and have high melting points.

Explanation

Bromine is one of the only two elements (along with mercury) that are liquid at room temperature.

The others listed are solid or gas under normal conditions.
