Problem
The properties which are common to both groups 1 and 17 elements in the periodic table are :
(1) Electropositive character increases down the groups
(2) Reactivity decreases from top to bottom in these groups
(3) Atomic radii increases as the atomic number increases
(4) Electronegativity decreases on moving down a group
