It is bromine as it has boiling point of 58.78 and has -7.2 melting point.

Why it is 58.78 -7.2 melting point?
(Fri, Mar 4, 2011 07:36:33 AM)
Because of its high melting point.

Bromin is redcoloured liquid.

With an increase in the atomic number the vander waals forces of attractions between the molecules increase so the physical state changes. Therefore, Bromine is liquid at room temparature.

Due to increase of vander waals forces, accordingly high melting point.

Because it is its physical property.

Vandrwall s forces is not responsible for remaining liquid in room temperature
generally bromine has the specific property which it itself remains constant without change of any thing where as the other ones changes gradually due to raise in room temperature.

Akash is right.

Bromine is the only liquid non metal at room temperature while in case of metals it is mercury and of couse you all are also right. Manzoor explained it right and also revathi.

Ya of course, mercury is also a liquid. But bromine is the only liquid metalloid !

Ya, I am with M. Vishali.

Mercury is a metal used in thermometers and bromine is a nonmetal.
Metal, non metal is the difference between mercury and bromine.

It is one of only 2 elements in periodic table that are liquids at room temperature (mercury is the other, although caesium, gallium, and rubidium melt just above room temperature).

The molecules of a liquid are held together by a collection of forces, see reference. Physical chemistry is the field which would let you calculate how strong those forces are for a particular molecule, and therefore how much kinetic energy each molecule must have to break those bonds and move more freely as a gas. For bromine, at 1 atmosphere pressure, that happens to be 332K, well above room temperature.

Mercury is a metal but bromine is not a metal.
It is used in thermometers.
(Fri, Aug 31, 2012 02:32:48 PM)
br is anon metal and mope ever other options are not related.

It's melting point is much lower then room temperature,
