Going from fluorine to chlorine, bromine and iodine, the electronegativity
Changes randomly
Increases
First decreases then increases
Decreases
Electronegativity decreases down the group.
The non-metal which exists in the liquid state at room temperature is :
(a) fluorine
(b) chlorine
(c) bromine
(d) iodine
why is fluorine more electronegative than chlorine,bromine and iodine?
