. Which element has the highest electronegativity

A: C

B: Mg

C: O

D: S


Best Answer


Electronegativity of an atom is defined as its tendency to attract a shared pair of electrons towards itself in a covalent bond.

The electronegativity increases on moving along the period from left to right and decreases on moving  down the group from top to bottom.

Thus, the electronegativity of O will be the highest amongst the given options.


Final Answer:

Hence, the correct option is C: O.
