Answer 2

Answer:

In group 1 of periodic table three elements X,Y and Z have atomic radii 133pm, 95pm and 65pm respectively giving a reason arrange them in the increasing order of their atomic number in the group.In group 1 of periodic table three elements X,Y and Z have atomic radii 133pm, 95pm and 65pm respectively giving a reason arrange them in the increasing order of their atomic number in the group.In group 1 of periodic table three elements X,Y and Z have atomic radii 133pm, 95pm and 65pm respectively giving a reason arrange them in the increasing order of their atomic number in the group.
