Test: BITSAT Mock Test- 12 - Question 56

The atomic radius of elements of which of these would be nearly same

Detailed Solution for Test: BITSAT Mock Test- 12 - Question 56

The atomic radii of the d- block elements of a given series decrease with increase in atomic number but this decrease becomes small after midway. The decrease in atomic radii in the beginning, is due to an increase in nuclear charge from member to member which tends to reduce the size. At the same time, the addition of extra electrons to (n-1)d orbitals also provides the screening effect. As the number of d-electrons increases, the screening effect increases. Thus, there are operating two effects namely screening effect and nuclear charge effect which oppose each other. In the midway onwards of the series both these effects become nearly equal and thus, there is no change in atomic radii inspite of the fact that atomic number increases gradually.

In Asia and much of the third World, trees are still destroyed in the old-fashioned way:they are cut down for fuel and cropland. In Europe , there is new and potentially more deadly culprit. The German call it ' Waldsterben' , the dying forest syndrome. But the diseases is far more than German phenomenon.Since it was first observed by German scientists in the autumn of 1980 , the mysterious malady has raced across Europe, blighting woods in countries as far apart as Sweden and Italy.
Explanations for the epidemic range from a cyclic change in the environment to a baffling form of tree cancer. But the most convincing evidence points to air pollution . Indeed, saving the rapidly deteriorating forests of Europe will probably require a two-pronged strategy : an offensive campaign that includes the breeding of pollution immune trees and a defensive scheme that calls for reductions in toxic emissions. But both will require more money than is currently being spent on such measures, as well as total commitment to protecting the enviornment .
