Bromine has a high melting point Yes so it melts very easily due to which it remains liquid at room temperature. The element was isolated independently by two chemists, Carl Jacob Lowig and Antoine Jerome Balard, in 1825"1826.

Elemental bromine is a fuming red-brown liquid at room temperature, corrosive and toxic, with properties between those of chlorine and iodine. Free bromine does not occur in nature, but occurs as colorless soluble crystalline mineral halite salts, analogous to table salt. @Sanjay, this is your answer learn carefully. So, that's it for bromine explanation.

Why is bromine having higher boiling point than fluorine?

Because.

The reason for this is that the physical attractive energy between bromine molecules is greater than that between fluorine molecules. The attraction between the molecules has to be overcome when boiling takes place. The type of attraction, in this case, is the Van der Waals attraction, being higher for bromine molecules because bromine molecules are much bigger, therefore having stronger transient dipoles (fluctuating dipoles due to the mobility of the electron density around the molecules).

At ambient temperature bromine is a brownish-red liquid. It has a similarly colored vapor with an offensive and suffocating odor. It is the only nonmetallic element that is liquid under ordinary conditions, it evaporates easily at standard temperature and pressures in a red vapor that has a strong disagreeable odor resembling that of chlorine. Bromine is less active chemically than chlorine and fluorine but is more active than iodine; its compounds are similar to those of the other halogens. Bromine is soluble in organic solvents and in water.

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.

Bromine is a non-metal and remains liquid at room temperature.

Its atomic no is 35 and atomic weight is 79.904

Bromine is a liquid because the intermolecular forces are strong enough so that it does not vaporise. Br forms diatomic molecules and van der Waals interactions are sufficiently strong.

The uses of bromine is :

Bromine compounds are used as pesticides, dyestuffs, water purification compounds, and as flame-retardants in plastics. 1, 2-dibromoethane is used as an anti-knock agent to raise the octane number of gasoline and allow engines to run more smoothly.

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.

Phosphorous is solid at room temperature.

Chlorine can either be gas or solid (chlorine tablets used for purifying water) and helium has gaseous nature in room temperature.

Bromine only is found in liquid form at room temp having brownish color.

Bromine is a liquid because the intermolecular forces are strong enough. So, that it does no vapourised.

Br forms diatomic molecules and van der Waals interaction are sufficiently strong, and it belongs to the halogen group.

The chemical element with the atomic number 35, Bromine is a non metal that remains liquid at room temperature. Mercury also remains liquid at room temperature but it is a metal. Bromine is the third lightest halogen.
