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 an..

This is a reaction in which an atom or a group of atoms present in a molecule gets displaced by another atom. a) Displacement of a less active metal by a more reactive one i) When a piece of iron is added to a solution of copper (II) sulphate, iron displaces..

Displacement of the Halogens by Chlorine - 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 gr..

. The eighth element from nitrogen is phosphorus and both these elements are similar in properties. Based on this observation, Newland stated his law of octaves thus 'when elements are arranged in increasing order of their atomic mass, the eighth element resembles the first in physical an..

Introduction - We have learnt about the motion of objects based on the definition of displacement, velocity and acceleration. Now let us see the causes that influence the motion of bodies. Have you wondered why certain natural phenomena occur and why they continue to occur in the same way..

Mendeleev's Periodic Law - Later, Mendeleev arranged the sixty-three elements known at that time in the increasing order of the atomic masses, in the form of a table called the Periodic Table. The periodic table further classified the elements by arranging the elements with similar proper..

Stokes' law explains why the speed of a raindrop is less than a freely falling body with constant velocity, from the height of clouds. The same law helps a man coming down with the help of a parachute, to slow down. Terminal velocity refers to the constant velocity, acquire..

Law of Polygon of Vectors - This law is used to add more than two vectors. The above figure illustrates four vectors Each of these vectors is displaced parallel to itself so that all four of them touch each other as shown in the figure (b). Obviously vector will be the..
