elements of group dynamics stage

Several types of microphones depend for their action upon the voltage induced in a conductor moving in a magnetic field. The dynamic or moving-coil micro- phone contains a small coil attached to a diaphragm, so arranged that when the diaphragm vibrates, the coil moves back and forth in a..

The state of equilibrium is a state in which the measurable properties of the system do not undergo any noticeable change under a particular set of conditions. We have seen that all observable properties of a system become constant at equilibrium. It may lead us to think that the reaction stops a..

In the long form of the periodic table, elements are grouped into four main blocks, purely on the basis of electronic configurations. Elements are grouped in blocks 's', 'p', 'd' and 'f' depending on the nature of orbital(s) into which the last electron..

. Some species of dinosaurs had feathers, although they could not fly using the feathers. Birds seem to have later adapted the feathers to flight. This, of course, means that birds are very closely related to reptiles, since dinosaurs were reptiles! The analysis of the organ structure in fossils al..

Elements - "An element is a pure substance which is made up of only one kind of atoms having the same atomic number." "The smallest particle of an element is the atom which, has all the properties of that element." "An element..

Some similar elements are separated and dissimilar elements are grouped together e.g., copper and mercury have similar properties but are placed in different groups. On the other hand elements of group IA such as lithium, sodium and potas..

These consist of all 's' and 'p' block elements excluding the noble gases (group 18 elements). The chemical properties of the representative elements are determined by the number of valence electrons in their atoms. The number of valence electrons belonging t..

Similar physical and chemical properties are shown by elements in a group. However the first member of each group differs from its succeeding members (called congeners). This mainly occurs because of, The small size of the atom and its ion. The high ionization en..

Physical Characteristics of Group 15 Elements - The important physical constants of group 15 elements are given bel..
