Akash Patel said: (Dec 14, 2010)  
It is bromine as it has boiling point of 58.78 and has -7.2 melting point.

Jai Varsheni said: (Jan 17, 2011)  
Why it is 58.78 -7.2 melting point?

Vinayagam said: (Mar 4, 2011)  
Because of its high melting point.

Vng said: (Apr 25, 2011)  
Bromin is redcoloured liquid.

Revathi Krishna said: (May 14, 2011)  
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.

B. Sai Sarvani said: (May 14, 2011)  
Due to increase of vander waals forces, accordingly high melting point.

Mohitjha15Feb @Gmail.Com said: (Jun 14, 2011)  
Because it is its physical property.

K.Manzoor said: (Jul 17, 2011)  
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.

Sunil said: (Jul 24, 2011)  
Akash is right.

Tin said: (Aug 29, 2011)  
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.

M.Vishali said: (Oct 7, 2011)  
Ya of course, mercury is also a liquid. But bromine is the only liquid metalloid !

Bharat said: (Oct 31, 2011)  
Ya, I am with M. Vishali.

Pankaj said: (Jan 13, 2012)  
Mercury is a metal used in thermometers and bromine is a nonmetal.

Metal, non metal is the difference between mercury and bromine.

Bannappa (Cvr) said: (Jan 14, 2012)  
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).

Rutul said: (Apr 4, 2012)  
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.

Narendra said: (Apr 13, 2012)  
Mercury is a metal but bromine is not a metal.
It is used in thermometers.

Shiva said: (Aug 31, 2012)  
br is anon metal and mope ever other options are not related.

Akhilesh said: (Oct 9, 2012)  
It's melting point is much lower then room temperature,

Nabilah said: (Apr 19, 2013)  
Chlorine become what in room temperature?

Vamsi said: (Aug 24, 2013)  
Mercury and Bromine are two elements that exist in liquid state at room temperature. Mercury is a metal & Bromine is a non-metal.

Sascha said: (Oct 22, 2013)  
Is there any small definition?

Kimberly said: (Nov 15, 2013)  
Bromine is a chemical element with the symbol Br, and atomic number of 35. It is in the halogen group. The element was isolated independently by two chemists, Carl Jacob Lowig and Antoine Jerome Balard.

Thamizh said: (Nov 20, 2013)  
Bromine is non metal which exist liquid in room temp.

Ganza said: (Jan 13, 2014)  
What is bromine? But answer is right.

Atharv Goel said: (Jan 19, 2014)  
Because it has 58.78 and -7.2 melting point.

Vuppala Rajesh said: (Jan 20, 2014)  
Bromines melting point is low so it is in that state in room temperature.

Jeevi said: (Jan 31, 2014)  
Because of its low melting point.

Kuenzang said: (Feb 20, 2014)  
Bromine is non metal in liquid state @room temperature. And mercury is metal in liquid state @room temperature of bromine vander waal's increase as atomic number increases.

Sakshi Vaid said: (Mar 4, 2014)  
It is one of only two elements on the periodic table that are known to be liquids at room temperature (mercury is the other, although caesium, gallium, and rubidium melt just above room temperature).

Dharmendra Singh said: (Mar 7, 2014)  
Bromine is correct because it is non metal.

Rakesh said: (Mar 11, 2014)  
That's what they are asking that which is a non metal that remains please.

Ankita said: (May 2, 2014)  
What is the other use of bromine?

Shubham Kango said: (May 18, 2014)  
These are used in TVs, furniture, and even mobile phone.

Gokul said: (May 28, 2014)  
Bromine was discovered independently by two chemists, Carl Jacob Lowig and Antoine Balard, in 1825 and 1826.

Rohit said: (Jul 2, 2014)  
Can anyone tell me. What is the vander wall?

Rahul Elr said: (Jul 28, 2014)  
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.

Chinelo said: (Oct 7, 2014)  
Can anyone tell me how bromine in used in mobile phones?

Makhan Kumar said: (Oct 31, 2014)  
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.

Nagesh said: (Nov 11, 2014)  
Bromine is a brown coloured liquid.

Nagesh said: (Nov 11, 2014)  
To exist a molecule together (group of atoms) there is some forces are working that force may be strong electrostatic force or force due to electron transformation or week van der waal forces.

Suriya said: (Nov 14, 2014)  
This is a non-metal, it is reddish brown.

Shatrudhan Kumar said: (Nov 17, 2014)  
Bromine is a non metal, which is at room temperature in liquid state.

Sana said: (Nov 17, 2014)  
Water freezing point 0° c or boiling point 100° c.

Ranga said: (May 8, 2015)  
Level of dissolve in water at room temp also consider on this and how this can be effected?

Usha said: (Jun 12, 2015)  
What the uses of bromine?

Saleh Balocj said: (Jun 24, 2015)  
How many chemical bonds of bromine?

Siva said: (Jul 6, 2015)  
Why bromine is liquid at room temperature?

Sushovan said: (Aug 17, 2015)  
Bromine is a liquid non-metal which stays liquid in room temperature.

Sowmiya said: (Aug 26, 2015)  
Mercury is liquid metal, where as bromine is a liquid in non-metals because of it's melting point and boiling point in the room temperature.

Shirish said: (Sep 11, 2015)  
Bromine is a liquid.

Sanjay Hembram said: (Sep 23, 2015)  
Who is name give Bromine? please tell me.

Arvind said: (Nov 14, 2015)  
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.

Aero said: (Dec 26, 2015)  
Bromine cools down when it is brought near a magnet.

Mansi said: (Feb 4, 2016)  
Is bromine a liquid?

Deepthi said: (Feb 22, 2016)  
Yes it is a liquid.

Arunjyothi B said: (Mar 3, 2016)  
Bromine is a liquid halogen nonmetal may be due to weak nuclear attraction on the outermost orbit.

Sudhanshu Kumar said: (Mar 7, 2016)  
It's Bromine.

Hridoi Borah said: (Apr 9, 2016)  
It is because of it's electronic configuration.

Yahya said: (May 12, 2016)  
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.

Sreeja said: (May 16, 2016)  
What are the uses of bromine?

Srishti said: (Jul 6, 2016)  
Why it has high melting point than others?

Ajay Sutar said: (Jul 26, 2016)  
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.

Ajay Sutar said: (Jul 26, 2016)  
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).

A.V.Deepashriii said: (Aug 20, 2016)  
Excellent information!

Chirag said: (Aug 30, 2016)  
No! The correct answer is mercury because it is only a metal that is liquid, bromine is not liquid.

Leki Wangmo said: (Sep 14, 2016)  
According to me, Mercury is the liquid in the room temperature but from the following answers, it is bromine.

Ryhshabbs said: (Sep 17, 2016)  
Mercury is a metal that found at room temperature.

Neymar Jr said: (Nov 15, 2016)  
It's bromine because it converts in a liquid state when its kept at room temperature it is also a non-metal.

Irshad said: (Dec 15, 2016)  
Bromine is right, I agree.

Ankur said: (Jan 8, 2017)  
Yes, bromine is right. Agree.

Noor said: (Jan 15, 2017)  
Bromine is liquid and it is not a metal.

Thanks for all other information.

Sweety said: (Mar 5, 2017)  
Bromine & mercury both are liquid. Why bromine can't be used in thermometers instead of mercury?

Salahuddin Zardi said: (Apr 23, 2017)  
Bromine is non-metal but there is a exemption that it us liquid at room temperature as mercury.

Yazraj said: (May 13, 2017)  
Bromine, it is the only non-metal to exits in liquid form at room temperature.

Miku said: (Jun 13, 2017)  
Yes, you are Right, Thanks @Akash.
