Answers (1)
Electronegativity -
Variation of Electronegativity
-
In moving from top to bottom in a group the atomic size increases thus the force of attraction decreases and hence the electronegativity decreases.
-
In moving from left to right in a period, the atomic size decreases and effective nuclear charge increases, thus the electronegativity increases.
-
Halogens are the most electronegative elements and fluorine has the highest electronegativity.
-
The electronegativity of any element decreases down the group. Thus carbon is the most electronegative element.
Therefore, Option(1) is correct
