What is cl2 made of?

At standard temperature and pressure, two chlorine atoms form the diatomic molecule Cl2. This is a pale yellow-green gas that has its distinctive strong smell, the smell of bleach. The bonding between the two atoms is relatively weak (only of 242.580 ±0.004 kJ/mol) which makes the Cl2 molecule highly reactive.

What Colour is bromine?

Bromine is a naturally occurring element that is a liquid at room temperature. It has a brownish-red color with a bleach-like odor, and it dissolves in water.

What is CI on the periodic table?

Chlorine – Element information, properties and uses | Periodic Table.

Is bromine a metal?

Smelly element No. 35, bromine, is a fairly abundant element but has a rare property: it is the only nonmetal to exist in liquid form at room temperature, and one of only two elements (the other being mercury) that is liquid at room temperature and pressure.

What is Cl2 used for?

Chlorine (Cl2) is widely used in many industrial applications. In the process industries it is used to treat cooling water. It is also injected directly into fired heater stacks in order to reduce sulfur emissions. (The sulfur monochloride that is formed is a solid and can be safely removed.)

How do you test for bromine?

A sensitive test for bromine is the reaction with fluorescein to give a deep red colour caused by bromination of the organic molecule, or by its reaction with fuchsine dyes in the presence of sulfurous acid, to give a deep blue colour.

What bromine is used for?

Bromine is used in many areas such as agricultural chemicals, dyestuffs, insecticides, pharmaceuticals and chemical intermediates. Some uses are being phased out for environmental reasons, but new uses continue to be found. Bromine compounds can be used as flame retardants.

How many protons are in the element bromine Br )?

What is bromine made of?

Natural bromine is a mixture of two stable isotopes: bromine-79 (50.54 percent) and bromine-81 (49.46 percent).
