valency of bromine

1. The properties of an element in the periodic table mainly depend on its outer electronic configuration, except in the case of transition elements. 2. Each period begins with an element having only one electron in the valence shell and ends with an element in which the valence..

The elements of this group form a variety of halides. The important features regarding the halides are: (i) Since fluorine is more electronegative than oxygen, its compounds with oxygen are called fluorides. For e.g., F 2 O is written as OF 2 and is named as oxygen difluoride. However, chlorine, ..

Halogens have only one electron less than the next noble gas. Therefore, they can get the noble gas configuration either by gaining one electron to form uninegative ion, X - , or by sharing electrons with other atoms. Thus, they show an oxidation of state of l or + 1. Since fluorine is the most ele..

1.Chlorine is placed second after fluorine in group VIIA. 2. Other members of this group are fluorine, bromine, iodine and astatine (the last member is radioactive). 3. Members of this group are called 'halogens' meaning salt producers. 4. Atoms of halogens have seven electro..

The elements placed in group VIIA of the periodic table are called halogens. All these elements form salts called halides, e.g. NaCl, NaI, KCl, KI etc. Halogen is an ancient Greek word meaning 'salt producer'. Halogens have seven electrons in their valence shell and so are monovalent. ..

(i) A chlorine atom will gain an electron to become a chloride ion. (ii) Similarly, atoms of oxygen, nitrogen, sulphur, bromine, iodine, etc. can accept electrons and get converted to their respective ions. (iii) In some cases, cations of higher valency may accept e..

. Sulphuric acid has numerous applications. Polonium is a radioactive element. F, Cl, Br, I and At (group 17) constitute the halogen family. These elements are extremely reactive and as such they are found in the combined state only. They form halide salts of the MX type or covalent compounds with ..

Summary - Chlorine belongs to group VII A. Members of this group are called halogens which means 'salt producers'. Chlorine is a greenish yellow gas. Chlorine has seven electrons in its outer most shell and so has a valency of 1. Like other halogens chlorine is a strong oxidising agent. C..
