More electronegative element in each pair

O & F ⇒ Fluorine is more electronegative.

O & Br ⇒ Oxygen is more electronegative.

O & S ⇒ Oxygen is more electronegative

O & N ⇒ Oxygen is more electronegative

O & P ⇒ Oxygen is more electronegative

O & K ⇒ Oxygen is more electronegative

O & Ca ⇒ Oxygen is more electronegative

Explanation:

Electronegativity is the measure pf tendency to attract bond pair electrons towards itself in a covalent bond.

More electronegative element attract bond pair electron from less electronegative element.

Electronegativity increases along the peroid when we move from left to right in perodic table and decreses down the group or top to bottom in periodic table.

So Oxygen, Fluorine, Chlorine and Nitrogen are the most electronegative among the all elements in periodic table.
