The halogens are a specific group of nonmetals with some distinctive properties. ... As a group, halogens exhibit highly variable physical properties. Halogens range from solid (I2) to liquid (Br2) to gaseous (F2 and Cl2) at room temperature. The chemical properties are more uniform. The halogens have very...

The elements of Group 17, the Halogens, are a very similar set of non-metals. They all exist as diatomic molecules, X2, and oxidise metals to form halides. The halogen oxides are acidic, and the hydrides are covalent. ... Physical Properties...

The halogens are five non-metallic elements found in group 17 of the periodic table. The term "halogen" means "salt-former" and compounds containing halogens are called "salts". All halogens have 7 electrons in their outer shells, giving them an oxidation number of -1. The halogens exist, at room temperature,

ATOMIC AND PHYSICAL PROPERTIES OF THE GROUP 7 ELEMENTS (THE HALOGENS) ... This page explores the trends in some atomic and physical properties of the Group 7 elements (the halogens) - fluorine, chlorine, bromine and iodine. You will find separate sections below covering the trends in atomic radius, electronegativity,

We will do a similar test for solubilites of halogens (Cl2, Br2, and I2) in water and hexanes. Since the halogens have distinctive colors unlike the sodium halide salts, we can observe this solubilites properties in a single test tube.

Part II: Reactions Between Halogens and Halide Ion ... In this experiment we will test all six combinations of different halogens (Cl2, Br2, and I2) and halides (Cl-, Br-, and I-) to see which ones will react and which ones won't. In our example here, we will look at the possible reaction between the halogen Br2 and...

As the atomic structure of the halogens becomes more complex with increasing atomic weight there is a gradiation in physical properties. For example: Fluorine is a pale green gas of low density. Chlorine is a greenish-yellow gas 1.892 times as dense as fluorine.
