The electronic configuration of fluorine atom is 1s 2 2s 2 2p 5 and therefore, there are 14 electrons in the valence shell of F 2 molecule. The molecular orbital electronic configuration of the molecule is: F 2 : KK ( s 2s) 2 ( s *2s) 2 ( s 2p z ) 2 ( p 2p x ) 2 ( p 2p y ) 2 ( p..

Main Features of the Long Form of the Periodic Table - 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 ..

General Characteristics of Group - 1. Valence shell electrons On moving down the group the valence shell electrons remain the same. 2. Valency The valency of all the members of a particular group is same. 3. Properties of elements The members of a certain gro..

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, ch..

Fluorine atom has seven electrons in its valence shell and needs one electron to complete its octet. Hydrogen atom also has a tendency to share one electron to acquire configuration of helium. When the two atoms approach each other, the overlapping of 1s-orbital of hydrogen and..

Position of Chlorine in the Periodic Table - 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 producer..

Oxidation States - 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 ..

The elements placed in group 7 (VIIA) of the periodic table are called halogens or salt producers. 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..

. 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 ..
