Soddy and Fajan summarised the a and b - particle emission in the form of the law known as Group Displacement Law. "The emission of a - particle by an element results in the formation of a new element which lies two places to the left of the parent element and the emission of b ..

Halogens are the most electronegative elements. Fluorine is the most electronegative, followed by chlorine then bromine and then iodine. Fluorine being the most electronegative halogen can displace all the other elements of this group (chlorine, bromine and iodine) from the aque..

Summary - Hydrogen is the most abundant element in the universe. Hydrogen is also the lightest element in the universe. It has a vapour density of 1, which is 14.4 times lighter than air. Hydrogen is absent in the free state in the earth's atmosphere. But in the combined state it is found in water,..

Summary - Oxygen and sulphur belong to group VI A. Oxygen shows a valency of -2, while sulphur shows a valency of -2, +4 and +6. Industrially oxygen is manufactured by fractional distillation of liquid air free of dust particles and CO 2 . Oxides of mercury, silver and lead decompose to g..

When atoms / groups having lone pair of electrons are bonded by a single bond to the conjugated system, they displace electrons towards multiple bond..

. In a displacement reaction an atom or group present in a compound is replaced by another atom or group, without bringing any change in the structure of the molecule or compound In double displacement reactions two different atoms or groups of atom..

Application of Electrochemical Series [ECS] - 1) Higher the SRP, greater is the tendency to accept e - , higher is the tendency to get reduced and greater is the oxidizing power. Fluorine system (F 2 /F) - has the highest SRP and hence it possesses highest oxidising power and this increases down th..

When atoms / groups having lone pair of electrons are bonded by a single bond to the conjugated system, they displace electrons towards multiple bonds. This conjugation between electrons of single (H-C) bond with multiple bonds is called hyperconjugat..

. In a displacement reaction an atom or group present in a compound is replaced by another atom or group without bringing any change in the structure of the molecule or compound. In double decomposition reactions the constituents (radicals) of two compounds exchange th..
