The properties which are common to both ...

The properties which are common to both groups 1 and 17 elements in the periodic table are:

A

electropositive character incrases down the groups

B

Reactivity decrases from top to bottom in these grous

C

atomic radii incrases as the atomic number increases

D

Electronegativity decreases on moving down a group

Text Solution

Verified by Experts

The correct Answer is:
A, C, D
Statements (a), (c) and (d) are common to both the groups 1 and 17. statemennt (b) is true only for group 17 elements.

The main group elements i.e. representative elements complete their electron configuration using s and p electrons in the periodic table. These elements range from the most metallic to the most non-metallic with intermediate properties, the semi-metals, in between .The elements which occur at the two extremes of the periodic table are highly reactive and therefore, these highly reactive elements do not occur in free state : they usually occur in the combined forms. Beryllium and aluminium exhibit many properties which are similar, but, the two elements differ in :
