Question 48 (c)
(a) Electropositive nature of the element(s) increases down the group and decreases across the period
(b) Electronegativity of the element decreases down the group and increases across the period
(c) Atomic size increases down the group and decreases across a period (left to right)
(d) 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 with smallest atomic size.

Solution

All the elements with atomic numbers 3 to 9 lie in the 2nd period of the periodic table. Among all, Fluorine (F) with atomic number 9, lies to the extreme right and hence has the smallest atomic size.
It is the lightest halogen and most electronegative element.
