The following diagram shows a part of the periodic table in which the elements are arranged according to their atomic numbers. (The letters given here are not the chemical symbols of the elements):


(i) Which element has a bigger atom, a or f?


(ii) Which element has a higher valency, k or o?


(iii) Which element is more metallic, i or k?


(iv) Which element is more non-metallic, d or g?


(v) Select a letter which represents a metal of valency 2.


(vi) Select a letter which represents a non-metal of valency 2.

(i) an element has a bigger atom because when we move left to right the size of the atom decreases.

(ii)The valency of o element is 1 and k element is 3.


(iii) When we move from left to right the metallic character decreases, so element i is more metallic.


(iv) When we move left to right in the period then the non- metallic character increases, so element g is more non metallic.


(v) letter b represents a metal of valency 2.


(vi) letter f represents a non metal of valency 2.
