Which one of the following would you expect to have highest electronegativity ?
1 $\mathrm{Mg}$ (atomic number 12)
2 $\mathrm{S}$ (atomic number 16 )
3 $\mathrm{B}$ (atomic number 5 )
4 $\mathrm{Te}$ (atomic number 52)
Explanation:
Electronegativity decreases from top to bottom in a group and left to right increase in period. So, the sulphur has highest electronegative than $\mathrm{Mg}, \mathrm{B}$ and $\mathrm{Te}$.

The most electronegative element is
1 nitrogen
2 oxygen
3 fluorine
4 chlorine
Explanation:
The most electronegative element is fluorine. The tendency of an atom in a molecule to attract the shared pair of electron towards itself is known as electronegativity.
