The second and third members in each group of the transition elements have similar metallic radii. Assing reason.

The second and third members in a group of transition metals have similar atomic radii. Why ?

Wxplain the following giving suitable reson. (a). Transitin metals of 3d-series doe not react readily with dilute acids to liberate hydrogen although they have high negative reduction potential values. Explain. (b). The atomic radii of the elements in a transition series do not vary much while they do vary in the case of s and p-block elements. Explain. (c). The second and third members in each group of the transition elements group of the transition elements have similar atomic radii. Explain.

Which of the following pairs of elements have similar atpmic radii?

Assertion: Cu, Ag and Au lie in Group 11 of the periodic table. Hence their atomic radii are in the order CultAgltAu Reason: In any group iof the transition elements, the atomic radii increase as we move down the group.
