Question

Which is more electronegative fluorine or chlorine

Answer 1

Explanation:

The correct ans is Fluorine (F)

F(Fluorine),O(Oxygen),N(Nitrogen),Cl(Chlorine) are the most electronegative elements in the modern periodic table.

This is because the shell of fluorine is much smaller than chlorine. As a result, it attracts the electron of every element in modern periodic table. The atomic number of Chlorine is 17 and Fluorine is 9. Both the elements are halogens and contains 1 electron in their outermost shell. Bcoz of their size, which leads to decrease in atomic radius which leads to decrease in electron cloud and so Fluorine is the most electronegative element in the modern periodic table.

If you are satisfy with my ans then mark me as a brainlist

if there is something wrong then kindly rectify it.

Answer 2

ANSWER

FLUORINE IS MORE ELECTRONEGATIVE THAN CHLORINE

EXPLANATION

ELECTRO NEGATIVITY INCREASES ACROSS THE PERIOD BECAUSE THE ATOMIC SIZE DECREASES AND NUCLEAR PULL INCREASES AND ELECTRO NEGATIVITY DECREASES DOWN THE GROUP BECAUSE THE ATOMIC SIZE DECREASES.
