On moving along the period , the atomic radii decreases

As we move along the period, the atomic radii decreases. Which of the following group contradicts the above statement ?

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.

In the periodic table atomic radii ______ Same in the period for all elements Increases along the period Not predictable Decreases along the period

Choose the right properties of periodic table. (a) Atomic radius increases from top to bottom along a group. (b) Atomic radius decreases from left to right along a period. (c) Valency remains the same in a group. (d) lonisation energy increases on moving down a group.

The atomic size of an element increases down the group while along a period, it tends to decrease. Explain.

Assertion: Potassium has a bigger atomic radius than Lithium Reason :Atomic radius decreases along a period

With the increase in atomic numbers the atomic radii go on decreasing in case of
