the atomic number of three elements X,Y,Z present in group I of the periodic table are 1.34A,0.95A,1.58A respectively.arrange them in order of increasing metallic character

Q. In the periodic table, with the increase in atomic number the metallic character of an element?

(i) Electropositive nature of the element(s) increases down the group and decreases across the period
(ii) Electronegativity of the element decreases down the group and increases across the period
(iii) Atomic size increases down the group and decreases across a period (left to right)
(iv) Metallic character increases down the group and decreases across a period.
On the basis of the above trends of the Periodic Table, answer the following about the elements with atomic numbers 3 to 9.

Which is the element with the smallest atomic size

Q.

(i) Electropositive nature of the element(s) increases down the group and decreases across the period
(ii) Electronegativity of the element decreases down the group and increases across the period
(iii) Atomic size increases down the group and decreases across a period (left to right)
(iv) Metallic character increases down the group and decreases across a period.
On the basis of the above trends of the Periodic Table, answer the following about the elements with atomic numbers 3 to 9.

Name the element which shows maximum valency.

Q.

(a) In this ladder (Figure 5.2) symbols of elements are jumbled up. Rearrange these symbols of elements in the increasing order of their atomic number in the Periodic Table.

(b) Arrange them in the order of their group also.

Larger the atomic radius more easier it is to loose the valence electrons i.e higher the metallic character. thus as we move down the group metallic character increases. Thus the order will be Z>X>Y
