Which group of the periodic table contains maximum elements

Following statements regarding the periodic trends of chemical reactivity of alkali metals and halogens are given. Which of these statements give the correct picture?

Discuss a) Electronic configuration b) occurence c) chemical reactivity with reference to alkalimetals hence justify the inclusion of alkali metals in the same group.

A property which progressively increases down a group in the periodic table is :

Which physical property is lower for alkaline earth metals as compared to alkali metals of the same period ?

Identify the correct statements from the following. (i) In the periodic table, about 78% of elements are metals. (ii) In a group, the metallic character decreases from top to battom and in a period the non-metallic character decreases from left to right. (iii) The element Ho belongs to f-block.

The heavier members of 13 and 14 groups besides the group oxidation state also show another oxidation state which is two unit less than the group OS. Down the group decreasing, the stability state of higher OS increasing , and that of lower OS increasing. The concept which is commonly called inert pair effect has been used to explain many physical and chemical properties of the element of these groups. Heavier members of group 13 exhibit oxidation state.
