1.	The position of three elements X, Y and Z in the periodic table are shown below: (i) Which type of ion, cation or anion, will be formed by element X ? (ii) Which element, Y or z, has the atom of comparatively larger size ? Give reason in each case.
Answer» SOLUTION :(i) The valency of X is one. It has TENDENCY to lose one electron. Therefore, X will FORM cation. (ii) Y, because ATOMIC radius decreases across a period due to increase in the electrostatic force between electrons and NUCLEUS.
