group displacement law and examples

Group Displacement Law - 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 whi..

The displacement of a moving particle is its change of position in a particular direction. To know the displacement of a moving particle, we must know both the length and the direction of the line joining the two positions of the moving particle. Hence, the displacement..

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..

When a floating body like wood is placed in water, it sinks until the weight of water displaced by it is just equal to its own weight and then it floats. This leads us to the principle of floatati..

Introduction - We have learnt about the motion of objects based on the definition of displacement, velocity and acceleratio..

Let a particle be at the points A, B, C at three successive times t, t ' and t '' respectively. is the displacement vector from time t to t ' . is the displacement vector from time t ' to t '' . The total displacement vector is the sum or the resultant of indivi..

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 properties together and separating the elem..

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 resultant of . Thus, the ..
