The Halogens They lack only one electron to form a complete shell or subshell, and are extremely active chemically. Chemical activity increases as you move upward in the group, fluorine being the most active element in the Periodic Table. At room temperature, fluorine and chlorine are gases, bromine is liquid, and iodine is solid.They form diatomic molecules in the pure state. The halogens are poisonous, and chlorine gas and chlorine compounds have been used as chemical weapons.hey lack only one electron to form a complete shell or subshell, and are extremely active chemically.

Is iodine a solid a liquid or gas? Why is Chlorine a gas Bromine a liquid and Iodine a solid at room temperature? Van der waals forces are present in all three chlorine, bromine and iodine, however the strength of the van der waals forces depend on the number of electrons. The more electr…ons present, the stronger the van der waals forces.

Disinfectants Bromine Bromine is the only non-metallic element that is liquid at room temperature and standard pressure. It is a red liquid that easily evaporates and smells. Bromine is approximately 3,12 times heavier than water. At temperatures of 58,8 °C it becomes gaseous, whereas at –7,3 °C and lower temperatures it is a solid.

ATOMIC AND PHYSICAL PROPERTIES OF THE GROUP 7 ELEMENTS (THE HALOGENS) If you explore the graphs, you will find that fluorine and chlorine are gases at room temperature, bromine is a liquid and iodine a solid. Nothing very surprising there! Explaining the trends in melting point and boiling point All of the halogens exist as diatomic molecules-F2, Cl2, and so on. The intermolecular attractions between one molecule and its neighbours are van der Waals dispersion forces. Notice that the trend down the Group isn't tidy.

- The attractive forces are strong enough to hold the molecules close. But the molecules have enough kinetic energy to slide past each other, so bromine condenses to a liquid. In iodine, the electrons are so far from the nuclei that the electron clouds can easily distort. The London dispersion forces are strong.

- Bromine (from Greek: βρῶμος, bromos, brómos meaning-strong smelling or) stench is a chemical element with Symbol, br and atomic number. 35it is a. halogenromine is rarer than about three-quarters of elements in the Earth 's crust. The high solubility of bromide ions has caused its accumulation in the oceans, and commercially the element is easily extracted from brine pools, mostly in the United States, Israel and China.

Fluorine At room temperature, fluorine is a gas of diatomic molecules, pale yellow when pure (sometimes described as yellow-green). It has a characteristic pungent odor detectable at 20 ppb. Fluorine condenses into a bright yellow liquid at −188 °C (−306 °F), a transition temperature similar to those of oxygen and nitrogen.

Chem* Heavy Quiz 1. Like most substances, bromine exists in one of the three typical phases. Br2 has a normal melting point of −7.2°C and a normal boiling point of 59°C. The triple point for Br2 is −7.3°C and 40 torr, and the critical point is 320°C and 100 atm. Using this information, sketch a phase diagram for bromine indicating the points described above. (Do this on paper.

Bromine Bromine is a chemical element with symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured gas. Its properties are thus intermediate between those of chlorine and iodine.

The Facts About Chlorine 1 Chlorine is a yellow-green gas at room temperature. 2  Chlorine has a pungent, irritating odor similar to bleach that is detectable at low concentrations.  The density of chlorine gas is approximately 2.5 times greater than air, which will cause it to initially remain near the ground in areas with little air movement.
