Which elements are liquid at room temperature

Although, elements caesium (Cs), rubidium (Rb), Francium (Fr) and Gallium (Ga) become liquid at or just above room temperature. Mercury doesn't conduct heat or electricity as well as other members of its group. Most metals are solids at room temperature because they share their valence electrons with surrounding metal atoms. However Mercury hangs onto its 6 valence electrons tighter than any other atom.

Answer:

Bromine (Br)

Mercury (Hg)

Explanation:

Taking 25°C as the room temperature, there are only two elements that are remarkably liquid at room temperature; they are bromine, Br, (a nonmetal) and mercury, Hg, (a metal).

It is very surprisingly: the other 116 elements are either solid or gaseous at room temperature.

Nevertheless, a few degrees above 25° other elements will be liquid.

This is the case of:

Caesium (Cs), whose melting point is 28.4°C
Rubidium (Rb), whose melting point is 39°C
Francium (Fr): whose melting point is 27°C
Gallium (Ga): whose melting point is 30°C.

This information, of course, is found in tables which are available in internet and some textbooks.
